Given numbers are 646, 508, 625, 747
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(646, 508) = 164084
GCD(646, 508) = ( 646 x 508 ) / 164084
= 646 / 508
= 646
Step2:
LCM(2, 625) = 1250
GCD(2, 625) = ( 2 x 625 ) / 1250
= 2 / 625
= 2
Step3:
LCM(1, 747) = 747
GCD(1, 747) = ( 1 x 747 ) / 747
= 1 / 747
= 1
So, Greatest Common Divisor of 646, 508, 625, 747 is 1
