Given numbers are 642, 558, 925, 284

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

Apply this formula for all numbers.

Step1:

LCM(642, 558) = 59706

GCD(642, 558) = ( 642 x 558 ) / 59706

= 642 / 558

= 642

Step2:

LCM(6, 925) = 5550

GCD(6, 925) = ( 6 x 925 ) / 5550

= 6 / 925

= 6

Step3:

LCM(1, 284) = 284

GCD(1, 284) = ( 1 x 284 ) / 284

= 1 / 284

= 1

So, Greatest Common Divisor of 642, 558, 925, 284 is 1
