Given numbers are 778, 414, 138, 290

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

Apply this formula for all numbers.

Step1:

LCM(778, 414) = 161046

GCD(778, 414) = ( 778 x 414 ) / 161046

= 778 / 414

= 778

Step2:

LCM(2, 138) = 138

GCD(2, 138) = ( 2 x 138 ) / 138

= 2 / 138

= 2

Step3:

LCM(2, 290) = 290

GCD(2, 290) = ( 2 x 290 ) / 290

= 2 / 290

= 2

So, Greatest Common Divisor of 778, 414, 138, 290 is 2
