What are the HCF and lcm of two numbers?

The HCF and LCM of two numbers are 13 and 455 respectively. If one of the number lies between 75 and 125, then, that number is: 17. The H.C.F. and L.C.M. of two numbers are 12 and 336 respectively. If one of the numbers is 84, the other is 18.

How to calculate the LCM of two numbers 60 and 45?

To calculate the LCM of two numbers 60 and 45. Out of other ways, One way to find the LCM of given numbers is as below: List the prime factors of each number first. Then multiply each factor the most number of times it occurs in any number.

What is the least common multiple of two numbers?

In arithmetic, the least common multiple or LCM of two numbers say a and b, is denoted as LCM (a,b). And the LCM is the smallest or least positive integer that is divisible by both a and b. For example, let us take two positive integers 4 and 6. Multiples of 4 are: 4,8,12,16,20,24…

What is the product of two numbers whose HCF is 12?

It is given that the LCM of two numbers is 2520 and their HCF is 12. One of the number is 504 and let the other number be x, then applying the above formula LCM×HCF = product of two numbers, we get: 2520×12=504×x ⇒30240=504x ⇒x= 50430240 ⇒x=60

The HCF and LCM of two numbers are 21 and 4641, respectively. If one of the numbers lies between 200 and 300, then the two numbers are Let the numbers be 21a and 21b, where a and b are co-primes. Two co-primes with product 221 are 13 and 17 . Hence, the two numbers are 273 and 357. Was this answer helpful?

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.

How to find HCF using divisor method in Excel?
