Given numbers are 121, 815, 425, 798

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

Apply this formula for all numbers.

Step1:

LCM(121, 815) = 98615

GCD(121, 815) = ( 121 x 815 ) / 98615

= 121 / 815

= 121

Step2:

LCM(1, 425) = 425

GCD(1, 425) = ( 1 x 425 ) / 425

= 1 / 425

= 1

Step3:

LCM(1, 798) = 798

GCD(1, 798) = ( 1 x 798 ) / 798

= 1 / 798

= 1

So, Greatest Common Divisor of 121, 815, 425, 798 is 1
