What is the LCM of X and Y if the HCF is are?

Answer: Their lcm is xy/1.

What is the LCM of X and Y?

When y is a multiple of x, then the LCM of x and y is y.

How do you find HCF and LCM of X?

Always remember, LCM is always divisible by HCF. Now, find factors of 12 such that their common factor is only one i.e. find the co-prime factors of 12. Now multiply the numbers by their HCF. Therefore, 3 x 6 = 18 and 4 x 6 = 24.

What is the LCM and HCF of 8 9 and 25?

Hence, the L.C.M of these three numbers is 1800. Hence, L.C.M of 8, 9 and 25 is 1800 and H.C.F of 8, 9 and 25 is 1.

How do you find the HCF of 25 and 9?

FAQs on GCF of 9 and 25 The GCF of 9 and 25 is 1. To calculate the greatest common factor (GCF) of 9 and 25, we need to factor each number (factors of 9 = 1, 3, 9; factors of 25 = 1, 5, 25) and choose the greatest factor that exactly divides both 9 and 25, i.e., 1.

What is the HCF and lcm of the two numbers?

In all the three cases, we observe that the HCF of the two numbers is 1. As HCF x LCM = Product of the numbers we have LCM = Product of numbers/HCF = Product of the numbers since HCF = 1. Hence in case the two numbers are co-prime, their LCM will be the product of the numbers.

What is the HCF and lcm of 25 35 and 45?

From the above expression, we can say 5 is the only common factor for all the three numbers. Therefore, 5 is the HCF of 25, 35 and 45. Example: Find the Least Common Multiple of 36 and 44. Solution: Given, two numbers 36 and 44. Let us find out the LCM, by division method.

What is the meaning of HCF in math?

Terminology in concepts of HCF (Highest Common factor) or LCM (Lowest Common Multiple) : Factor or Divisor : A factor or divisor of a positive integer and it is divides it evenly parts of any positive integer ( i.e remainder is zero ).

What are the multiples of 5 HCF?

For example 10,15,20,25,30,35,40 …….. are multiples of 5 HCF (Highest Common factor) or GCD (Greatest Common Divisor): HCF of two or more than numbers is the greatest number (divisor) that divides all the given number exactly. So HCF is also called the greatest common divisor (GCD).
