Given numbers are 138, 908, 457, 570

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

Apply this formula for all numbers.

Step1:

LCM(138, 908) = 62652

GCD(138, 908) = ( 138 x 908 ) / 62652

= 138 / 908

= 138

Step2:

LCM(2, 457) = 914

GCD(2, 457) = ( 2 x 457 ) / 914

= 2 / 457

= 2

Step3:

LCM(1, 570) = 570

GCD(1, 570) = ( 1 x 570 ) / 570

= 1 / 570

= 1

So, Greatest Common Divisor of 138, 908, 457, 570 is 1
