Given numbers are 138, 851, 741, 657

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(138, 851) = 5106

GCD(138, 851) = ( 138 x 851 ) / 5106

= 138 / 851

= 138

Step2:

LCM(23, 741) = 17043

GCD(23, 741) = ( 23 x 741 ) / 17043

= 23 / 741

= 23

Step3:

LCM(1, 657) = 657

GCD(1, 657) = ( 1 x 657 ) / 657

= 1 / 657

= 1

So, Greatest Common Divisor of 138, 851, 741, 657 is 1
