Given numbers are 705, 840, 206, 831

The list of prime factors of all numbers are

Prime factors of 705 are 3 x 5 x 47

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

Prime factors of 206 are 2 x 103

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 705, 840, 206, 831

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

Apply this formula for all numbers.

Step1:

LCM(705, 840) = 39480

GCD(705, 840) = ( 705 x 840 ) / 39480

= 705 / 840

= 705

Step2:

LCM(15, 206) = 3090

GCD(15, 206) = ( 15 x 206 ) / 3090

= 15 / 206

= 15

Step3:

LCM(1, 831) = 831

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

= 1 / 831

= 1

So, Greatest Common Divisor of 705, 840, 206, 831 is 1
