Given numbers are 861, 703, 606, 138

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

Apply this formula for all numbers.

Step1:

LCM(861, 703) = 605283

GCD(861, 703) = ( 861 x 703 ) / 605283

= 861 / 703

= 861

Step2:

LCM(1, 606) = 606

GCD(1, 606) = ( 1 x 606 ) / 606

= 1 / 606

= 1

Step3:

LCM(1, 138) = 138

GCD(1, 138) = ( 1 x 138 ) / 138

= 1 / 138

= 1

So, Greatest Common Divisor of 861, 703, 606, 138 is 1
