GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(637, 172) = 109564
GCD(637, 172) = ( 637 x 172 ) / 109564
= 637 / 172
= 637
Step2:
LCM(1, 721) = 721
GCD(1, 721) = ( 1 x 721 ) / 721
= 1 / 721
= 1
Step3:
LCM(1, 967) = 967
GCD(1, 967) = ( 1 x 967 ) / 967
= 1 / 967
= 1
So, Greatest Common Divisor of 637, 172, 721, 967 is 1
