What is the LCM for 6 7 and 9?

Notice that, 9, 7, and 6 all go evenly into 126. 126/9=14 126/7=18 and 126/6=21 and 14, 18, and 21 don’t have a common factor.

What is the HCF of 17 and 19?

Of two prime numbers is 1 because prime numbers doesn’t any other factor except themselves and 1. So for all primes the HCF is 1. 17 and 19 are primes so the HCF of both the numbers is 1.

What is the LCM of 6 and 18?

Since the question is asking for the least common multiple, you factor out the 6 in 18 and 6. This gives you 631 as the LCM because you have factored out 6 and this is the GCF because there are no more common factors between 3 and 1. Since 631 equals 18, 18 is the LCM.

What are not prime numbers?

Nonprime numbers are integers that are not prime numbers, i.e. zero (0), units (e.g. one (1), minus one (–1)), composite numbers and the associates of prime numbers (negated primes). Some nonprime numbers are –2563, 1, 48 and 1729.

What is the LCM calculator?

Calculator Use The Least Common Multiple ( LCM ) is also referred to as the Lowest Common Multiple ( LCM ) and Least Common Divisor ( LCD) . For two integers a and b, denoted LCM(a,b), the LCM is the smallest positive integer that is evenly divisible by both a and b. For example, LCM(2,3) = 6 and LCM(6,10) = 30.
