Given numbers are 620, 838, 813, 753

The list of prime factors of all numbers are

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

Prime factors of 838 are 2 x 419

Prime factors of 813 are 3 x 271

Prime factors of 753 are 3 x 251

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

Given numbers are 620, 838, 813, 753

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

Apply this formula for all numbers.

Step1:

LCM(620, 838) = 259780

GCD(620, 838) = ( 620 x 838 ) / 259780

= 620 / 838

= 620

Step2:

LCM(2, 813) = 1626

GCD(2, 813) = ( 2 x 813 ) / 1626

= 2 / 813

= 2

Step3:

LCM(1, 753) = 753

GCD(1, 753) = ( 1 x 753 ) / 753

= 1 / 753

= 1

So, Greatest Common Divisor of 620, 838, 813, 753 is 1
