What is the HCF of 210?

To find the HCF of 210 and 55, we will find the prime factorization of the given numbers, i.e. 210 = 2 × 3 × 5 × 7; 55 = 5 × 11. ⇒ Since 5 is the only common prime factor of 210 and 55. Hence, HCF (210, 55) = 5.

How to calculate the LCM of 9, 15?

To calculate the LCM of 9 and 15 by the division method, we will divide the numbers (9, 15) by their prime factors (preferably common). The product of these divisors gives the LCM of 9 and 15. Step 1: Find the smallest prime number that is a factor of at least one of the numbers, 9 and 15.

How to find the least common multiple for 9, 10 and 15?

The Least Common Multiple (LCM) for 9, 10 and 15, notation LCM (9,10,15), is 90 Solution by Using the Division Method: This method consists of grouping by separating the numbers that will be decomposed on the right side by commas while on the left side we put the prime numbers that divide any of the numbers on the right side.

How to find the lcm by listing multiples?

How to Find LCM by Listing Multiples 1 List the multiples of each number until at least one of the multiples appears on all lists 2 Find the smallest number that is on all of the lists 3 This number is the LCM

How to find the LCM using the greatest common factor?

How to Find the LCM Using the Greatest Common Factor The formula to find the using the Greatest Common Factor GCF of a set of numbers is: LCM (a,b) = (a×b)/GCF (a,b) Example: Find LCM (6,10) 1 Find the GCF (6,10) = 2 2 Use the LCM by GCF formula to calculate (6×10)/2 = 60/2 = 30 3 So LCM (6,10) = 30 See More….
