Given numbers are 817, 122, 617, 120

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

Apply this formula for all numbers.

Step1:

LCM(817, 122) = 99674

GCD(817, 122) = ( 817 x 122 ) / 99674

= 817 / 122

= 817

Step2:

LCM(1, 617) = 617

GCD(1, 617) = ( 1 x 617 ) / 617

= 1 / 617

= 1

Step3:

LCM(1, 120) = 120

GCD(1, 120) = ( 1 x 120 ) / 120

= 1 / 120

= 1

So, Greatest Common Divisor of 817, 122, 617, 120 is 1
