Given numbers are 642, 196, 634, 843

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

Apply this formula for all numbers.

Step1:

LCM(642, 196) = 62916

GCD(642, 196) = ( 642 x 196 ) / 62916

= 642 / 196

= 642

Step2:

LCM(2, 634) = 634

GCD(2, 634) = ( 2 x 634 ) / 634

= 2 / 634

= 2

Step3:

LCM(2, 843) = 1686

GCD(2, 843) = ( 2 x 843 ) / 1686

= 2 / 843

= 2

So, Greatest Common Divisor of 642, 196, 634, 843 is 1
