Given numbers are 122, 157, 403, 790

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

Apply this formula for all numbers.

Step1:

LCM(122, 157) = 19154

GCD(122, 157) = ( 122 x 157 ) / 19154

= 122 / 157

= 122

Step2:

LCM(1, 403) = 403

GCD(1, 403) = ( 1 x 403 ) / 403

= 1 / 403

= 1

Step3:

LCM(1, 790) = 790

GCD(1, 790) = ( 1 x 790 ) / 790

= 1 / 790

= 1

So, Greatest Common Divisor of 122, 157, 403, 790 is 1
