You need at least two numbers to find an LCM. It doesn't matter whether they are prime or composite.
They are 2 and 140 because their LCM is 140 and their product is 280
They could be: 17 and 149
10 and 35
As written, no numbers satisfy those conditions. 6 and 36 have a GCF of 6 and an LCM of 36.
6,364 and 9
They are 4 and 9
Not normally because the LCM of numbers are found by multiplying their highest prime factors

When the numbers are relatively prime.
20 and 100.GCF is 20, and LCM is 100.
When the numbers are relatively prime.
LCM of 7 and 13Since 7 and 13 are both prime numbers, or numbers whose only factors are 1 and itself, the LCM can be found by multiplying 7 and 13 together. The answer will be 91.Though multiplying the numbers together when working with composite numbers MIGHT work, it only works 100% of the time when both numbers are prime. If one or both numbers are composite (have more factors than 1 and itself), multiples should be listed until a common one is found. That number will be the LCM.The LCM of 7 and 13 is 91.
well, look at the factors of 16...we have 2,4,8, and16.So if we had LCM of 8 and 16, that would be 16 an both are composite
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.
60, 120 and 1440 have a GCF of 60 and an LCM of 1440. I'm not sure what the "times 4" refers to.
12 and 66
