Given numbers are 835, 620, 806, 490

The list of prime factors of all numbers are

Prime factors of 835 are 5 x 167

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

Prime factors of 806 are 2 x 13 x 31

Prime factors of 490 are 2 x 5 x 7 x 7

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

Given numbers are 835, 620, 806, 490

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

Apply this formula for all numbers.

Step1:

LCM(835, 620) = 103540

GCD(835, 620) = ( 835 x 620 ) / 103540

= 835 / 620

= 835

Step2:

LCM(5, 806) = 4030

GCD(5, 806) = ( 5 x 806 ) / 4030

= 5 / 806

= 5

Step3:

LCM(1, 490) = 490

GCD(1, 490) = ( 1 x 490 ) / 490

= 1 / 490

= 1

So, Greatest Common Divisor of 835, 620, 806, 490 is 1
