Given numbers are 138, 885, 246, 638

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

Apply this formula for all numbers.

Step1:

LCM(138, 885) = 40710

GCD(138, 885) = ( 138 x 885 ) / 40710

= 138 / 885

= 138

Step2:

LCM(3, 246) = 246

GCD(3, 246) = ( 3 x 246 ) / 246

= 3 / 246

= 3

Step3:

LCM(3, 638) = 1914

GCD(3, 638) = ( 3 x 638 ) / 1914

= 3 / 638

= 3

So, Greatest Common Divisor of 138, 885, 246, 638 is 1
