4 and 9 7 and 8
They are 2 and 140 because their LCM is 140 and their product is 280
30 and 3
The product of the GCF and LCM of a pair of numbers is equal to the product of the numbers.
To find the LCM, you multiply the numbers together and then divide by the HCF. In this case, we don't know the numbers, but we have the HCF (13) and we have the product of the numbers (1690). Thus all you do is divide 1690 by 13 to get: 1690/13 = 130 And thus the LCM of two numbers whose hcf is 13 and product is 1690 is 130.
4 and 9 11 and 12
10 and 28
They are: 2 and 140
The LCM of 4 and 6 is 12.
The product of the original numbers is equal to the product of the GCF and LCM. Divide the product of the LCM and GCF by the one number. The answer will be the other.
Numbers that are relatively prime have their LCM as their product.
The product of the GCF and LCM of two numbers is equal to the product of the two numbers. The other number is 126.
