Given numbers are 630, 368, 389, 115
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(630, 368) = 115920
GCD(630, 368) = ( 630 x 368 ) / 115920
= 630 / 368
= 630
Step2:
LCM(2, 389) = 778
GCD(2, 389) = ( 2 x 389 ) / 778
= 2 / 389
= 2
Step3:
LCM(1, 115) = 115
GCD(1, 115) = ( 1 x 115 ) / 115
= 1 / 115
= 1
So, Greatest Common Divisor of 630, 368, 389, 115 is 1
