Given numbers are 686, 404, 235, 102
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(686, 404) = 138572
GCD(686, 404) = ( 686 x 404 ) / 138572
= 686 / 404
= 686
Step2:
LCM(2, 235) = 470
GCD(2, 235) = ( 2 x 235 ) / 470
= 2 / 235
= 2
Step3:
LCM(1, 102) = 102
GCD(1, 102) = ( 1 x 102 ) / 102
= 1 / 102
= 1
So, Greatest Common Divisor of 686, 404, 235, 102 is 1
