Given numbers are 138, 859, 568, 765

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

Apply this formula for all numbers.

Step1:

LCM(138, 859) = 118542

GCD(138, 859) = ( 138 x 859 ) / 118542

= 138 / 859

= 138

Step2:

LCM(1, 568) = 568

GCD(1, 568) = ( 1 x 568 ) / 568

= 1 / 568

= 1

Step3:

LCM(1, 765) = 765

GCD(1, 765) = ( 1 x 765 ) / 765

= 1 / 765

= 1

So, Greatest Common Divisor of 138, 859, 568, 765 is 1
