Why is it that the LCM and the GFC seem to be opposites of the same thing?

Very astute. The LCM and the GCF have an inverse relationship. Since their product equals the product of the original two numbers, the larger the GCF gets, the smaller the LCM is and vice versa.


What is the gfc and LCM of 86 129 and 215 show sullotion?

First, Its the gcf not the gfc Gcf : | 86 129 215 129 is a prime number so GCF= 1 LCM: 86 x 129x 215 =2385210


What numbers do you get when the gfc is 11 the LCM is 231?

33 and 77 have a GCF of 11 and an LCM of 231.


What are 2 numbers with a gfc of 6 and a LCM of 210?

4 and 6


What are two numbers if the gfc is 9 and the LCM is 126?

Why is 36 not the LCM of 12?

12 and what? the LCM of any number is itself example 2 and 12 the LCM is 12 same thing 4 and 12, the LCM is 12 8 and 12 LCM is 24... etc


What number pair has an LCM of 36 and a gfc of 1?

The pair of numbers whose GCF is 1 and LCM is 36 is 9 and 4. The numbers should be greater than their GCF and less than their LCM.


How is lcd and gcd related to LCM and gcf?

GCD and GCF are the same thing. Factors and divisors are interchangeable. The LCD and the LCM are the same process with different results. The LCD produces a denominator, the LCM produces a whole number.


What pair of numbers have an LCM of 36 and a gfc of 3?

3 and 36 9 and 12


Does 6 and 8 have the same LCM?

No.A single number does not have an LCM, only a set of number can have an LCM. So 6 does not have an LCM and 8 does not have an LCM. If neither number have an LCM, they cannot have the same LCM.However, the C in LCM stands for COMMON and so the LCM is a multiple that they share.6 and 9 have a different LCM to 6 and 8.


How can the LCM be equal to the greatest number in the set?

If the other numbers are all factors of the greatest number, then that number will be the LCM. Example: 2, 4 & 8: both 2 and 4 are factors of 8, so 8 is the LCM. 2, 3 and 12: same thing, both 2 & 3 are factors of 12.


Can a number have the LCM and the gcf the same number?

Only if you're comparing the number to itself. The LCM and GCF of 10 and 10 is 10.
