Given numbers are 138, 657, 691, 371
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(138, 657) = 30222
GCD(138, 657) = ( 138 x 657 ) / 30222
= 138 / 657
= 138
Step2:
LCM(3, 691) = 2073
GCD(3, 691) = ( 3 x 691 ) / 2073
= 3 / 691
= 3
Step3:
LCM(1, 371) = 371
GCD(1, 371) = ( 1 x 371 ) / 371
= 1 / 371
= 1
So, Greatest Common Divisor of 138, 657, 691, 371 is 1
