Given numbers are 311, 202, 720, 840

The list of prime factors of all numbers are

Prime factors of 311 are 311

Prime factors of 202 are 2 x 101

Prime factors of 720 are 2 x 2 x 2 x 2 x 3 x 3 x 5

Prime factors of 840 are 2 x 2 x 2 x 3 x 5 x 7

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

Given numbers are 311, 202, 720, 840

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

Apply this formula for all numbers.

Step1:

LCM(311, 202) = 62822

GCD(311, 202) = ( 311 x 202 ) / 62822

= 311 / 202

= 311

Step2:

LCM(1, 720) = 720

GCD(1, 720) = ( 1 x 720 ) / 720

= 1 / 720

= 1

Step3:

LCM(1, 840) = 840

GCD(1, 840) = ( 1 x 840 ) / 840

= 1 / 840

= 1

So, Greatest Common Divisor of 311, 202, 720, 840 is 1
