Given numbers are 831, 340, 220, 786

The list of prime factors of all numbers are

Prime factors of 831 are 3 x 277

Prime factors of 340 are 2 x 2 x 5 x 17

Prime factors of 220 are 2 x 2 x 5 x 11

Prime factors of 786 are 2 x 3 x 131

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

Given numbers are 831, 340, 220, 786

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

Apply this formula for all numbers.

Step1:

LCM(831, 340) = 282540

GCD(831, 340) = ( 831 x 340 ) / 282540

= 831 / 340

= 831

Step2:

LCM(1, 220) = 220

GCD(1, 220) = ( 1 x 220 ) / 220

= 1 / 220

= 1

Step3:

LCM(1, 786) = 786

GCD(1, 786) = ( 1 x 786 ) / 786

= 1 / 786

= 1

So, Greatest Common Divisor of 831, 340, 220, 786 is 1
