GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(686, 156) = 53508
GCD(686, 156) = ( 686 x 156 ) / 53508
= 686 / 156
= 686
Step2:
LCM(2, 374) = 374
GCD(2, 374) = ( 2 x 374 ) / 374
= 2 / 374
= 2
Step3:
LCM(2, 826) = 826
GCD(2, 826) = ( 2 x 826 ) / 826
= 2 / 826
= 2
So, Greatest Common Divisor of 686, 156, 374, 826 is 2
