Is it possible to have two numbers whose HCF is 18 and LCM?

No, it is not possible to have two numbers whose HCF is 18 and LCM is 760. Since, HCF must be a factor of LCM, but 18 is not factor of 760.

Is it possible to have HCF and LCM?

No, since HCF does not divide LCM exactly. HCF always divides the LCM completely.

Is it possible that two numbers have 12 as their HCF and 350 as their LCM explain?

False. Reason: We know that HCF should divide LCM. But, the HCF 12 does not divide the LCM 350.

Can two numbers have HCF 12 and LCM 512?

No, they cannot have 512 as their L.C.M. We know that the H.C.F. is one of the factors of the L.C.M. Here, 3, which is a factor of 12, is not a factor of 512.

What is the HCF of 12 and 64?

4
Therefore, the GCF of 12 and 64 is 4.

How do you find the LCM of 20 and 24?

Steps to find LCM

1. Find the prime factorization of 20. 20 = 2 × 2 × 5.
2. Find the prime factorization of 24. 24 = 2 × 2 × 2 × 3.
3. LCM = 2 × 2 × 2 × 3 × 5.
4. LCM = 120.

Is it possible to have two number whose HCF?

Answer Expert Verified It is NOT possible to have two numbers whose HCF is 18 and LCM is 760. The number 760 is not completely divisible by 18. We know that hcf of two numbers is always a divisor of lcm of those two numbers.

Can two numbers have HCF 6 and LCM 630?

NO, it is not possible.

Can two numbers have 12 as their HCF and 340 as their LCM?

HCF of two numbers must be a factor of LCM of those numbers . According to the question, HCF = 12 and LCM = 340 . But 340 is not divisible by 12. So, two numbers cannot have 12 and 340 as their HCF and LCM.

What is the difference between HCF and LCM?

The HCF is the common factor for both numbers whereas the LCM contains all the unique factors of both numbers. So, 2 x 2 or 4 is a common factor for both numbers. The factors remaining are 7 and 9. So, 7 is a factor of one number and 9 is the factor of the second number.

What is the product of HCF and lcm of 270?

HCF of two numbers is 3 and LCM of those numbers is 90. Now product of HCF and LCM = 270. Is there anyway to find out those numbers? Now find the factors of 270 and verify Y is for yes and N is for no (3, 90), (6, 45), (9, 30) and (15, 18). All the above mentioned pairs of numbers have 3 as HCF and 90 as LCM.

How to find the HCF of more than 3 numbers?

The above steps can also be used to find the HCF of more than 3 numbers. Example: Find the HCF of 144 and 160 by division method. Since 160>144, so the dividend will be 160 and the divisor will be 144. Hence, we can see here 16 is the highest number which divides 160 and 144. To calculate the LCM of two numbers 60 and 45.

What is the least common multiple of 8 and 12?

You can see, the least common multiple or the smallest common multiple of two numbers, 8 and 12 is 24. The formula which involves both HCF and LCM is: A x B = H.C.F. (A,B) x L.C.M. (A,B) How to find HCF and LCM? Here are the methods we can use to find the HCF and LCM of given numbers. Let us learn both methods, one by one.
