GCD of numbers is the greatest common divisor

So, the GCD (71, 55, 22, 68) = 1.

Given numbers are 71, 55, 22, 68

The list of prime factors of all numbers are

Prime factors of 71 are 71

Prime factors of 55 are 5 x 11

Prime factors of 22 are 2 x 11

Prime factors of 68 are 2 x 2 x 17

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

Given numbers are 71, 55, 22, 68

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

Apply this formula for all numbers.

Step1:

LCM(71, 55) = 3905

GCD(71, 55) = ( 71 x 55 ) / 3905

= 71 / 55

= 71

Step2:

LCM(1, 22) = 22

GCD(1, 22) = ( 1 x 22 ) / 22

= 1 / 22

= 1

Step3:

LCM(1, 68) = 68

GCD(1, 68) = ( 1 x 68 ) / 68

= 1 / 68

= 1

So, Greatest Common Divisor of 71, 55, 22, 68 is 1
