GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(681, 144) = 32688
GCD(681, 144) = ( 681 x 144 ) / 32688
= 681 / 144
= 681
Step2:
LCM(3, 137) = 411
GCD(3, 137) = ( 3 x 137 ) / 411
= 3 / 137
= 3
Step3:
LCM(1, 969) = 969
GCD(1, 969) = ( 1 x 969 ) / 969
= 1 / 969
= 1
So, Greatest Common Divisor of 681, 144, 137, 969 is 1
