GCD of numbers is the greatest common divisor

So, the GCD (68, 91, 26, 51) = 1.

Given numbers are 68, 91, 26, 51

The list of prime factors of all numbers are

Prime factors of 68 are 2 x 2 x 17

Prime factors of 91 are 7 x 13

Prime factors of 26 are 2 x 13

Prime factors of 51 are 3 x 17

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 68, 91, 26, 51

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(68, 91) = 6188

GCD(68, 91) = ( 68 x 91 ) / 6188

= 68 / 91

= 68

Step2:

LCM(1, 26) = 26

GCD(1, 26) = ( 1 x 26 ) / 26

= 1 / 26

= 1

Step3:

LCM(1, 51) = 51

GCD(1, 51) = ( 1 x 51 ) / 51

= 1 / 51

= 1

So, Greatest Common Divisor of 68, 91, 26, 51 is 1
