Given numbers are 686, 390, 959, 626
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(686, 390) = 133770
GCD(686, 390) = ( 686 x 390 ) / 133770
= 686 / 390
= 686
Step2:
LCM(2, 959) = 1918
GCD(2, 959) = ( 2 x 959 ) / 1918
= 2 / 959
= 2
Step3:
LCM(1, 626) = 626
GCD(1, 626) = ( 1 x 626 ) / 626
= 1 / 626
= 1
So, Greatest Common Divisor of 686, 390, 959, 626 is 1
