Given numbers are 642, 545, 504, 606

The list of prime factors of all numbers are

Prime factors of 642 are 2 x 3 x 107

Prime factors of 545 are 5 x 109

Prime factors of 504 are 2 x 2 x 2 x 3 x 3 x 7

Prime factors of 606 are 2 x 3 x 101

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

Given numbers are 642, 545, 504, 606

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

Apply this formula for all numbers.

Step1:

LCM(642, 545) = 349890

GCD(642, 545) = ( 642 x 545 ) / 349890

= 642 / 545

= 642

Step2:

LCM(1, 504) = 504

GCD(1, 504) = ( 1 x 504 ) / 504

= 1 / 504

= 1

Step3:

LCM(1, 606) = 606

GCD(1, 606) = ( 1 x 606 ) / 606

= 1 / 606

= 1

So, Greatest Common Divisor of 642, 545, 504, 606 is 1
