Given numbers are 615, 781, 620, 853

The list of prime factors of all numbers are

Prime factors of 615 are 3 x 5 x 41

Prime factors of 781 are 11 x 71

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

Prime factors of 853 are 853

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

Given numbers are 615, 781, 620, 853

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

Apply this formula for all numbers.

Step1:

LCM(615, 781) = 480315

GCD(615, 781) = ( 615 x 781 ) / 480315

= 615 / 781

= 615

Step2:

LCM(1, 620) = 620

GCD(1, 620) = ( 1 x 620 ) / 620

= 1 / 620

= 1

Step3:

LCM(1, 853) = 853

GCD(1, 853) = ( 1 x 853 ) / 853

= 1 / 853

= 1

So, Greatest Common Divisor of 615, 781, 620, 853 is 1
