What is the LCM of 3 and 9?

Least common multiple (LCM) of 3 and 9 is 9.

How do u find the LCM?

One way to find the least common multiple of two numbers is to first list the prime factors of each number. Then multiply each factor the greatest number of times it occurs in either number. If the same factor occurs more than once in both numbers, you multiply the factor the greatest number of times it occurs.

What is the LCM of 10 15 and 3?

The LCM of 3,10,15 3 , 10 , 15 is the result of multiplying all prime factors the greatest number of times they occur in either number. The LCM of 3,10,15 3 , 10 , 15 is 2⋅3⋅5=30 2 ⋅ 3 ⋅ 5 = 30 .

What is the GCF of 9 15 and 24?

There is one 3 in 24 and in 15 and two in 9 – so one 3 is common to all three numbers. There is a 5 in 15 but not in 9 or 24, so the GCF doesn’t have a 5. And there are no more prime numbers. This means our GCF = 3.

What is the GCF of 9 and 18?

We found the factors and prime factorization of 9 and 18. The biggest common factor number is the GCF number. So the greatest common factor 9 and 18 is 9.
