Given numbers are 642, 570, 275, 544

The list of prime factors of all numbers are

Prime factors of 642 are 2 x 3 x 107

Prime factors of 570 are 2 x 3 x 5 x 19

Prime factors of 275 are 5 x 5 x 11

Prime factors of 544 are 2 x 2 x 2 x 2 x 2 x 17

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

Given numbers are 642, 570, 275, 544

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

Apply this formula for all numbers.

Step1:

LCM(642, 570) = 60990

GCD(642, 570) = ( 642 x 570 ) / 60990

= 642 / 570

= 642

Step2:

LCM(6, 275) = 1650

GCD(6, 275) = ( 6 x 275 ) / 1650

= 6 / 275

= 6

Step3:

LCM(1, 544) = 544

GCD(1, 544) = ( 1 x 544 ) / 544

= 1 / 544

= 1

So, Greatest Common Divisor of 642, 570, 275, 544 is 1
