Given numbers are 440, 858, 997, 553

The list of prime factors of all numbers are

Prime factors of 440 are 2 x 2 x 2 x 5 x 11

Prime factors of 858 are 2 x 3 x 11 x 13

Prime factors of 997 are 997

Prime factors of 553 are 7 x 79

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

Given numbers are 440, 858, 997, 553

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

Apply this formula for all numbers.

Step1:

LCM(440, 858) = 17160

GCD(440, 858) = ( 440 x 858 ) / 17160

= 440 / 858

= 440

Step2:

LCM(22, 997) = 21934

GCD(22, 997) = ( 22 x 997 ) / 21934

= 22 / 997

= 22

Step3:

LCM(1, 553) = 553

GCD(1, 553) = ( 1 x 553 ) / 553

= 1 / 553

= 1

So, Greatest Common Divisor of 440, 858, 997, 553 is 1
