Given numbers are 771, 520, 442, 550

The list of prime factors of all numbers are

Prime factors of 771 are 3 x 257

Prime factors of 520 are 2 x 2 x 2 x 5 x 13

Prime factors of 442 are 2 x 13 x 17

Prime factors of 550 are 2 x 5 x 5 x 11

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

Given numbers are 771, 520, 442, 550

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

Apply this formula for all numbers.

Step1:

LCM(771, 520) = 400920

GCD(771, 520) = ( 771 x 520 ) / 400920

= 771 / 520

= 771

Step2:

LCM(1, 442) = 442

GCD(1, 442) = ( 1 x 442 ) / 442

= 1 / 442

= 1

Step3:

LCM(1, 550) = 550

GCD(1, 550) = ( 1 x 550 ) / 550

= 1 / 550

= 1

So, Greatest Common Divisor of 771, 520, 442, 550 is 1
