Given numbers are 642, 279, 428, 341

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

Apply this formula for all numbers.

Step1:

LCM(642, 279) = 59706

GCD(642, 279) = ( 642 x 279 ) / 59706

= 642 / 279

= 642

Step2:

LCM(3, 428) = 1284

GCD(3, 428) = ( 3 x 428 ) / 1284

= 3 / 428

= 3

Step3:

LCM(1, 341) = 341

GCD(1, 341) = ( 1 x 341 ) / 341

= 1 / 341

= 1

So, Greatest Common Divisor of 642, 279, 428, 341 is 1
