Given numbers are 312, 507, 638
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(312, 507) = 4056
GCD(312, 507) = ( 312 x 507 ) / 4056
= 312 / 507
= 312
Step2:
LCM(39, 638) = 24882
GCD(39, 638) = ( 39 x 638 ) / 24882
= 39 / 638
= 39
So, Greatest Common Divisor of 312, 507, 638 is 1
