Given numbers are 778, 404, 121, 435

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

Apply this formula for all numbers.

Step1:

LCM(778, 404) = 157156

GCD(778, 404) = ( 778 x 404 ) / 157156

= 778 / 404

= 778

Step2:

LCM(2, 121) = 242

GCD(2, 121) = ( 2 x 121 ) / 242

= 2 / 121

= 2

Step3:

LCM(1, 435) = 435

GCD(1, 435) = ( 1 x 435 ) / 435

= 1 / 435

= 1

So, Greatest Common Divisor of 778, 404, 121, 435 is 1
