Given numbers are 921, 642, 199, 863

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

Apply this formula for all numbers.

Step1:

LCM(921, 642) = 197094

GCD(921, 642) = ( 921 x 642 ) / 197094

= 921 / 642

= 921

Step2:

LCM(3, 199) = 597

GCD(3, 199) = ( 3 x 199 ) / 597

= 3 / 199

= 3

Step3:

LCM(1, 863) = 863

GCD(1, 863) = ( 1 x 863 ) / 863

= 1 / 863

= 1

So, Greatest Common Divisor of 921, 642, 199, 863 is 1
