GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(311, 921) = 286431
GCD(311, 921) = ( 311 x 921 ) / 286431
= 311 / 921
= 311
Step2:
LCM(1, 392) = 392
GCD(1, 392) = ( 1 x 392 ) / 392
= 1 / 392
= 1
Step3:
LCM(1, 812) = 812
GCD(1, 812) = ( 1 x 812 ) / 812
= 1 / 812
= 1
So, Greatest Common Divisor of 311, 921, 392, 812 is 1
