Given numbers are 138, 230, 568, 979

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

Apply this formula for all numbers.

Step1:

LCM(138, 230) = 690

GCD(138, 230) = ( 138 x 230 ) / 690

= 138 / 230

= 138

Step2:

LCM(46, 568) = 13064

GCD(46, 568) = ( 46 x 568 ) / 13064

= 46 / 568

= 46

Step3:

LCM(2, 979) = 1958

GCD(2, 979) = ( 2 x 979 ) / 1958

= 2 / 979

= 2

So, Greatest Common Divisor of 138, 230, 568, 979 is 1
