Given numbers are 631, 172, 963, 921
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(631, 172) = 108532
GCD(631, 172) = ( 631 x 172 ) / 108532
= 631 / 172
= 631
Step2:
LCM(1, 963) = 963
GCD(1, 963) = ( 1 x 963 ) / 963
= 1 / 963
= 1
Step3:
LCM(1, 921) = 921
GCD(1, 921) = ( 1 x 921 ) / 921
= 1 / 921
= 1
So, Greatest Common Divisor of 631, 172, 963, 921 is 1
