A factor of a number will divide that number evenly. A common factor is any factor which two numbers share. One of the numbers here is 1. The only number that can divide evenly in to is 1. Therefore, it doesn't matter what the other number is, the HCF can only be 1.
The GCF is 1.
The HCF is: 2
The GCF is 1.
Yes: product of a & b = LCM x HCF so b = (LCM x HCF)/a
The HCF is: 2
To have a HCF, you need at least 2 numbers. There is no HCF in just 1 number.
factors of 8: 1, 2, 4, 8 factors of 18: 1, 2, 3, 6, 9, 18 HCF: 2
The HCF of 78, 98 and 168 is 2.
The GCF is 1.
1. The factors of 2 are 1 & 2. The factors of 11 are 1 & 11.
Factors of 26 - 1, 2, 13, 26 Factors of 54 - 1, 2, 3, 6, 9, 18, 27, 54 HCF = 2
77 and 1
Both 3 and 2 are prime. This means they cannot be broken down further into prime factors. As they are different, this means they will not have any common prime factors. Therefore the HCF of 3 and 2 is 1. The HCF of any two different prime numbers will always be 1.
The HCF is 1.
The GCF is 1.
It is 1 but the HCF is 2
The HCF is: 2
