Given numbers are 684, 916, 815, 790
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(684, 916) = 156636
GCD(684, 916) = ( 684 x 916 ) / 156636
= 684 / 916
= 684
Step2:
LCM(4, 815) = 3260
GCD(4, 815) = ( 4 x 815 ) / 3260
= 4 / 815
= 4
Step3:
LCM(1, 790) = 790
GCD(1, 790) = ( 1 x 790 ) / 790
= 1 / 790
= 1
So, Greatest Common Divisor of 684, 916, 815, 790 is 1
