Given numbers are 642, 476, 305, 552

The list of prime factors of all numbers are

Prime factors of 642 are 2 x 3 x 107

Prime factors of 476 are 2 x 2 x 7 x 17

Prime factors of 305 are 5 x 61

Prime factors of 552 are 2 x 2 x 2 x 3 x 23

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

Given numbers are 642, 476, 305, 552

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

Apply this formula for all numbers.

Step1:

LCM(642, 476) = 152796

GCD(642, 476) = ( 642 x 476 ) / 152796

= 642 / 476

= 642

Step2:

LCM(2, 305) = 610

GCD(2, 305) = ( 2 x 305 ) / 610

= 2 / 305

= 2

Step3:

LCM(1, 552) = 552

GCD(1, 552) = ( 1 x 552 ) / 552

= 1 / 552

= 1

So, Greatest Common Divisor of 642, 476, 305, 552 is 1
