Given numbers are 948, 128, 21, 425

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

Apply this formula for all numbers.

Step1:

LCM(948, 128) = 30336

GCD(948, 128) = ( 948 x 128 ) / 30336

= 948 / 128

= 948

Step2:

LCM(4, 21) = 84

GCD(4, 21) = ( 4 x 21 ) / 84

= 4 / 21

= 4

Step3:

LCM(1, 425) = 425

GCD(1, 425) = ( 1 x 425 ) / 425

= 1 / 425

= 1

So, Greatest Common Divisor of 948, 128, 21, 425 is 1
