Given numbers are 620, 155, 847, 846

The list of prime factors of all numbers are

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

Prime factors of 155 are 5 x 31

Prime factors of 847 are 7 x 11 x 11

Prime factors of 846 are 2 x 3 x 3 x 47

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

Given numbers are 620, 155, 847, 846

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

Apply this formula for all numbers.

Step1:

LCM(620, 155) = 620

GCD(620, 155) = ( 620 x 155 ) / 620

= 620 / 155

= 620

Step2:

LCM(155, 847) = 131285

GCD(155, 847) = ( 155 x 847 ) / 131285

= 155 / 847

= 155

Step3:

LCM(1, 846) = 846

GCD(1, 846) = ( 1 x 846 ) / 846

= 1 / 846

= 1

So, Greatest Common Divisor of 620, 155, 847, 846 is 1
