Given numbers are 309, 502, 639, 630
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(309, 502) = 155118
GCD(309, 502) = ( 309 x 502 ) / 155118
= 309 / 502
= 309
Step2:
LCM(1, 639) = 639
GCD(1, 639) = ( 1 x 639 ) / 639
= 1 / 639
= 1
Step3:
LCM(1, 630) = 630
GCD(1, 630) = ( 1 x 630 ) / 630
= 1 / 630
= 1
So, Greatest Common Divisor of 309, 502, 639, 630 is 1
