Given numbers are 642, 267, 884, 398

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

Apply this formula for all numbers.

Step1:

LCM(642, 267) = 57138

GCD(642, 267) = ( 642 x 267 ) / 57138

= 642 / 267

= 642

Step2:

LCM(3, 884) = 2652

GCD(3, 884) = ( 3 x 884 ) / 2652

= 3 / 884

= 3

Step3:

LCM(1, 398) = 398

GCD(1, 398) = ( 1 x 398 ) / 398

= 1 / 398

= 1

So, Greatest Common Divisor of 642, 267, 884, 398 is 1
