Given numbers are 620, 553, 843, 955

The list of prime factors of all numbers are

Prime factors of 620 are 2 x 2 x 5 x 31

Prime factors of 553 are 7 x 79

Prime factors of 843 are 3 x 281

Prime factors of 955 are 5 x 191

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

Given numbers are 620, 553, 843, 955

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

Apply this formula for all numbers.

Step1:

LCM(620, 553) = 342860

GCD(620, 553) = ( 620 x 553 ) / 342860

= 620 / 553

= 620

Step2:

LCM(1, 843) = 843

GCD(1, 843) = ( 1 x 843 ) / 843

= 1 / 843

= 1

Step3:

LCM(1, 955) = 955

GCD(1, 955) = ( 1 x 955 ) / 955

= 1 / 955

= 1

So, Greatest Common Divisor of 620, 553, 843, 955 is 1
