Given numbers are 842, 280, 831, 857

The list of prime factors of all numbers are

Prime factors of 842 are 2 x 421

Prime factors of 280 are 2 x 2 x 2 x 5 x 7

Prime factors of 831 are 3 x 277

Prime factors of 857 are 857

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

Given numbers are 842, 280, 831, 857

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

Apply this formula for all numbers.

Step1:

LCM(842, 280) = 117880

GCD(842, 280) = ( 842 x 280 ) / 117880

= 842 / 280

= 842

Step2:

LCM(2, 831) = 1662

GCD(2, 831) = ( 2 x 831 ) / 1662

= 2 / 831

= 2

Step3:

LCM(1, 857) = 857

GCD(1, 857) = ( 1 x 857 ) / 857

= 1 / 857

= 1

So, Greatest Common Divisor of 842, 280, 831, 857 is 1
