GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(747, 298) = 222606
GCD(747, 298) = ( 747 x 298 ) / 222606
= 747 / 298
= 747
Step2:
LCM(1, 927) = 927
GCD(1, 927) = ( 1 x 927 ) / 927
= 1 / 927
= 1
Step3:
LCM(1, 638) = 638
GCD(1, 638) = ( 1 x 638 ) / 638
= 1 / 638
= 1
So, Greatest Common Divisor of 747, 298, 927, 638 is 1
