Given numbers are 657, 246, 309, 641
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(657, 246) = 53874
GCD(657, 246) = ( 657 x 246 ) / 53874
= 657 / 246
= 657
Step2:
LCM(3, 309) = 309
GCD(3, 309) = ( 3 x 309 ) / 309
= 3 / 309
= 3
Step3:
LCM(3, 641) = 1923
GCD(3, 641) = ( 3 x 641 ) / 1923
= 3 / 641
= 3
So, Greatest Common Divisor of 657, 246, 309, 641 is 1
