Given numbers are 921, 737, 639, 457

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

Apply this formula for all numbers.

Step1:

LCM(921, 737) = 678777

GCD(921, 737) = ( 921 x 737 ) / 678777

= 921 / 737

= 921

Step2:

LCM(1, 639) = 639

GCD(1, 639) = ( 1 x 639 ) / 639

= 1 / 639

= 1

Step3:

LCM(1, 457) = 457

GCD(1, 457) = ( 1 x 457 ) / 457

= 1 / 457

= 1

So, Greatest Common Divisor of 921, 737, 639, 457 is 1
