5
The GCF is 25.
It is: 3 to 7 by dividing both by their HCF which is 5
The GCF is 35.
The GCF is 7.
5=5x1 35=5x7 HCF=5
The common factors of 15 and 75 are: 1, 3, 5, and 15 of which 15 is the HCF of 15 and 75
The HCF is 7.
The GCF is 1.
It is: 35
The HCF is 7.
Oh honey, the Highest Common Factor (HCF) of 5 and 7 is 1 because those two numbers don't have any common factors other than 1. The Lowest Common Multiple (LCM) of 5 and 7 is simply the product of the two numbers, which is 35. So there you have it, simple math for a simple question!
