The set of three numbers whose LCM (Least Common Multiple) is equal to the product of the numbers would be {1, 2, 2}.
Here's how it works:
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.
10 and 28
The product of the GCF and LCM of two numbers is equal to the product of the two numbers. The other number is 126.
Any pair of prime numbers. 5 and 7 11 and 13
No. You can only find the LCM of at least two numbers, prime or otherwise. The LCM of any two prime numbers is their product.
They are 2 and 140 because their LCM is 140 and their product is 280

The product of the GCF and LCM of a pair of numbers is equal to the product of the numbers.
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.
When the numbers are co-prime, ie have no common factor. Simplest example is 2 & 3 whose LCM is 6
The product of the GCF and LCM of two numbers is equal to the product of the two numbers. The other number is 126.
The LCM of a set of prime numbers is their product.
Any pair of prime numbers. 5 and 7 11 and 13
Numbers that are relatively prime have their LCM as their product.
