Given numbers are 309, 208, 649, 939
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(309, 208) = 64272
GCD(309, 208) = ( 309 x 208 ) / 64272
= 309 / 208
= 309
Step2:
LCM(1, 649) = 649
GCD(1, 649) = ( 1 x 649 ) / 649
= 1 / 649
= 1
Step3:
LCM(1, 939) = 939
GCD(1, 939) = ( 1 x 939 ) / 939
= 1 / 939
= 1
So, Greatest Common Divisor of 309, 208, 649, 939 is 1
