Given numbers are 102, 842, 428

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

Apply this formula for all numbers.

Step1:

LCM(102, 842) = 42942

GCD(102, 842) = ( 102 x 842 ) / 42942

= 102 / 842

= 102

Step2:

LCM(2, 428) = 428

GCD(2, 428) = ( 2 x 428 ) / 428

= 2 / 428

= 2

So, Greatest Common Divisor of 102, 842, 428 is 2
