Given numbers are 135, 618, 421, 556

The list of prime factors of all numbers are

Prime factors of 135 are 3 x 3 x 3 x 5

Prime factors of 618 are 2 x 3 x 103

Prime factors of 421 are 421

Prime factors of 556 are 2 x 2 x 139

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

Given numbers are 135, 618, 421, 556

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

Apply this formula for all numbers.

Step1:

LCM(135, 618) = 27810

GCD(135, 618) = ( 135 x 618 ) / 27810

= 135 / 618

= 135

Step2:

LCM(3, 421) = 1263

GCD(3, 421) = ( 3 x 421 ) / 1263

= 3 / 421

= 3

Step3:

LCM(1, 556) = 556

GCD(1, 556) = ( 1 x 556 ) / 556

= 1 / 556

= 1

So, Greatest Common Divisor of 135, 618, 421, 556 is 1
