Given numbers are 642, 594, 171, 625

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

Apply this formula for all numbers.

Step1:

LCM(642, 594) = 63558

GCD(642, 594) = ( 642 x 594 ) / 63558

= 642 / 594

= 642

Step2:

LCM(6, 171) = 342

GCD(6, 171) = ( 6 x 171 ) / 342

= 6 / 171

= 6

Step3:

LCM(3, 625) = 1875

GCD(3, 625) = ( 3 x 625 ) / 1875

= 3 / 625

= 3

So, Greatest Common Divisor of 642, 594, 171, 625 is 1
