Given numbers are 642, 555, 203, 882

The list of prime factors of all numbers are

Prime factors of 642 are 2 x 3 x 107

Prime factors of 555 are 3 x 5 x 37

Prime factors of 203 are 7 x 29

Prime factors of 882 are 2 x 3 x 3 x 7 x 7

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

Given numbers are 642, 555, 203, 882

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

Apply this formula for all numbers.

Step1:

LCM(642, 555) = 118770

GCD(642, 555) = ( 642 x 555 ) / 118770

= 642 / 555

= 642

Step2:

LCM(3, 203) = 609

GCD(3, 203) = ( 3 x 203 ) / 609

= 3 / 203

= 3

Step3:

LCM(1, 882) = 882

GCD(1, 882) = ( 1 x 882 ) / 882

= 1 / 882

= 1

So, Greatest Common Divisor of 642, 555, 203, 882 is 1
