Given numbers are 801, 831, 142, 520

The list of prime factors of all numbers are

Prime factors of 801 are 3 x 3 x 89

Prime factors of 831 are 3 x 277

Prime factors of 142 are 2 x 71

Prime factors of 520 are 2 x 2 x 2 x 5 x 13

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

Given numbers are 801, 831, 142, 520

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

Apply this formula for all numbers.

Step1:

LCM(801, 831) = 221877

GCD(801, 831) = ( 801 x 831 ) / 221877

= 801 / 831

= 801

Step2:

LCM(3, 142) = 426

GCD(3, 142) = ( 3 x 142 ) / 426

= 3 / 142

= 3

Step3:

LCM(1, 520) = 520

GCD(1, 520) = ( 1 x 520 ) / 520

= 1 / 520

= 1

So, Greatest Common Divisor of 801, 831, 142, 520 is 1
