Given numbers are 406, 801, 620, 831

The list of prime factors of all numbers are

Prime factors of 406 are 2 x 7 x 29

Prime factors of 801 are 3 x 3 x 89

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

Prime factors of 831 are 3 x 277

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

Given numbers are 406, 801, 620, 831

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

Apply this formula for all numbers.

Step1:

LCM(406, 801) = 325206

GCD(406, 801) = ( 406 x 801 ) / 325206

= 406 / 801

= 406

Step2:

LCM(1, 620) = 620

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

= 1 / 620

= 1

Step3:

LCM(1, 831) = 831

GCD(1, 831) = ( 1 x 831 ) / 831

= 1 / 831

= 1

So, Greatest Common Divisor of 406, 801, 620, 831 is 1
