Given numbers are 665, 890, 630, 778

The list of prime factors of all numbers are

Prime factors of 665 are 5 x 7 x 19

Prime factors of 890 are 2 x 5 x 89

Prime factors of 630 are 2 x 3 x 3 x 5 x 7

Prime factors of 778 are 2 x 389

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

Given numbers are 665, 890, 630, 778

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

Apply this formula for all numbers.

Step1:

LCM(665, 890) = 118370

GCD(665, 890) = ( 665 x 890 ) / 118370

= 665 / 890

= 665

Step2:

LCM(5, 630) = 630

GCD(5, 630) = ( 5 x 630 ) / 630

= 5 / 630

= 5

Step3:

LCM(5, 778) = 3890

GCD(5, 778) = ( 5 x 778 ) / 3890

= 5 / 778

= 5

So, Greatest Common Divisor of 665, 890, 630, 778 is 1
