Given numbers are 642, 444, 220, 541

The list of prime factors of all numbers are

Prime factors of 642 are 2 x 3 x 107

Prime factors of 444 are 2 x 2 x 3 x 37

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

Prime factors of 541 are 541

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

Given numbers are 642, 444, 220, 541

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

Apply this formula for all numbers.

Step1:

LCM(642, 444) = 47508

GCD(642, 444) = ( 642 x 444 ) / 47508

= 642 / 444

= 642

Step2:

LCM(6, 220) = 660

GCD(6, 220) = ( 6 x 220 ) / 660

= 6 / 220

= 6

Step3:

LCM(2, 541) = 1082

GCD(2, 541) = ( 2 x 541 ) / 1082

= 2 / 541

= 2

So, Greatest Common Divisor of 642, 444, 220, 541 is 1
