Given numbers are 131, 806, 842, 840

The list of prime factors of all numbers are

Prime factors of 131 are 131

Prime factors of 806 are 2 x 13 x 31

Prime factors of 842 are 2 x 421

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 131, 806, 842, 840

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

Apply this formula for all numbers.

Step1:

LCM(131, 806) = 105586

GCD(131, 806) = ( 131 x 806 ) / 105586

= 131 / 806

= 131

Step2:

LCM(1, 842) = 842

GCD(1, 842) = ( 1 x 842 ) / 842

= 1 / 842

= 1

Step3:

LCM(1, 840) = 840

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

= 1 / 840

= 1

So, Greatest Common Divisor of 131, 806, 842, 840 is 1
