Given numbers are 642, 101, 572, 436

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

Apply this formula for all numbers.

Step1:

LCM(642, 101) = 64842

GCD(642, 101) = ( 642 x 101 ) / 64842

= 642 / 101

= 642

Step2:

LCM(1, 572) = 572

GCD(1, 572) = ( 1 x 572 ) / 572

= 1 / 572

= 1

Step3:

LCM(1, 436) = 436

GCD(1, 436) = ( 1 x 436 ) / 436

= 1 / 436

= 1

So, Greatest Common Divisor of 642, 101, 572, 436 is 1
