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

Apply this formula for all numbers.

Step1:

LCM(492, 440) = 54120

GCD(492, 440) = ( 492 x 440 ) / 54120

= 492 / 440

= 492

Step2:

LCM(4, 128) = 128

GCD(4, 128) = ( 4 x 128 ) / 128

= 4 / 128

= 4

Step3:

LCM(4, 428) = 428

GCD(4, 428) = ( 4 x 428 ) / 428

= 4 / 428

= 4

So, Greatest Common Divisor of 492, 440, 128, 428 is 4
