Given numbers are 725, 156, 68, 220

The list of prime factors of all numbers are

Prime factors of 725 are 5 x 5 x 29

Prime factors of 156 are 2 x 2 x 3 x 13

Prime factors of 68 are 2 x 2 x 17

Prime factors of 220 are 2 x 2 x 5 x 11

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

Given numbers are 725, 156, 68, 220

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

Apply this formula for all numbers.

Step1:

LCM(725, 156) = 113100

GCD(725, 156) = ( 725 x 156 ) / 113100

= 725 / 156

= 725

Step2:

LCM(1, 68) = 68

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

= 1 / 68

= 1

Step3:

LCM(1, 220) = 220

GCD(1, 220) = ( 1 x 220 ) / 220

= 1 / 220

= 1

So, Greatest Common Divisor of 725, 156, 68, 220 is 1
