The product of the GCF and LCM of a pair of numbers is equal to the product of the numbers.
Any pair of prime numbers as for example 19 and 23
The GCF is 31.
3 and 18
The product of the GCF and the LCM of two numbers is equal to the product of the original two numbers. Multiply the GCF and the LCM. The original two numbers will be another factor pair of that total. Find the factor pair that has that GCF and LCM.
To find a pair of numbers with a given GCF, take the GCF number and double it. The pair of numbers is the GCF, and two times the GCF. For instance, two numbers with a GCF of 3 are 3 and 6.
The GCF is 1.
The GCF is a single number so there cannot be any pair of numbers in the answer.
The greatest common factor of the numbers 63, 105 and 294 is 21.
The greatest common factor of the numbers 105 and 245 is 35.
Any consecutive even numbers have a GCF of 2.
The product of the GCF and LCM of a pair of numbers is equal to the product of the numbers.
Any pair of prime numbers as for example 19 and 23
The GCF is 31.
8 and 16
6 and 9
They can be 18 and 27
