Given numbers are 291, 778, 396, 920

The list of prime factors of all numbers are

Prime factors of 291 are 3 x 97

Prime factors of 778 are 2 x 389

Prime factors of 396 are 2 x 2 x 3 x 3 x 11

Prime factors of 920 are 2 x 2 x 2 x 5 x 23

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 291, 778, 396, 920

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

Apply this formula for all numbers.

Step1:

LCM(291, 778) = 226398

GCD(291, 778) = ( 291 x 778 ) / 226398

= 291 / 778

= 291

Step2:

LCM(1, 396) = 396

GCD(1, 396) = ( 1 x 396 ) / 396

= 1 / 396

= 1

Step3:

LCM(1, 920) = 920

GCD(1, 920) = ( 1 x 920 ) / 920

= 1 / 920

= 1

So, Greatest Common Divisor of 291, 778, 396, 920 is 1
