Given numbers are 138, 628, 136, 579

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

Apply this formula for all numbers.

Step1:

LCM(138, 628) = 43332

GCD(138, 628) = ( 138 x 628 ) / 43332

= 138 / 628

= 138

Step2:

LCM(2, 136) = 136

GCD(2, 136) = ( 2 x 136 ) / 136

= 2 / 136

= 2

Step3:

LCM(2, 579) = 1158

GCD(2, 579) = ( 2 x 579 ) / 1158

= 2 / 579

= 2

So, Greatest Common Divisor of 138, 628, 136, 579 is 1
