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

Apply this formula for all numbers.

Step1:

LCM(428, 140) = 14980

GCD(428, 140) = ( 428 x 140 ) / 14980

= 428 / 140

= 428

Step2:

LCM(4, 98) = 196

GCD(4, 98) = ( 4 x 98 ) / 196

= 4 / 98

= 4

So, Greatest Common Divisor of 428, 140, 98 is 2
