Given numbers are 642, 469, 957, 515

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

Apply this formula for all numbers.

Step1:

LCM(642, 469) = 301098

GCD(642, 469) = ( 642 x 469 ) / 301098

= 642 / 469

= 642

Step2:

LCM(1, 957) = 957

GCD(1, 957) = ( 1 x 957 ) / 957

= 1 / 957

= 1

Step3:

LCM(1, 515) = 515

GCD(1, 515) = ( 1 x 515 ) / 515

= 1 / 515

= 1

So, Greatest Common Divisor of 642, 469, 957, 515 is 1
