Given numbers are 921, 925, 220, 423

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

Apply this formula for all numbers.

Step1:

LCM(921, 925) = 851925

GCD(921, 925) = ( 921 x 925 ) / 851925

= 921 / 925

= 921

Step2:

LCM(1, 220) = 220

GCD(1, 220) = ( 1 x 220 ) / 220

= 1 / 220

= 1

Step3:

LCM(1, 423) = 423

GCD(1, 423) = ( 1 x 423 ) / 423

= 1 / 423

= 1

So, Greatest Common Divisor of 921, 925, 220, 423 is 1
