Given numbers are 686, 511, 142, 675
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(686, 511) = 50078
GCD(686, 511) = ( 686 x 511 ) / 50078
= 686 / 511
= 686
Step2:
LCM(7, 142) = 994
GCD(7, 142) = ( 7 x 142 ) / 994
= 7 / 142
= 7
Step3:
LCM(1, 675) = 675
GCD(1, 675) = ( 1 x 675 ) / 675
= 1 / 675
= 1
So, Greatest Common Divisor of 686, 511, 142, 675 is 1
