Given numbers are 447, 520, 140, 857

The list of prime factors of all numbers are

Prime factors of 447 are 3 x 149

Prime factors of 520 are 2 x 2 x 2 x 5 x 13

Prime factors of 140 are 2 x 2 x 5 x 7

Prime factors of 857 are 857

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

Given numbers are 447, 520, 140, 857

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

Apply this formula for all numbers.

Step1:

LCM(447, 520) = 232440

GCD(447, 520) = ( 447 x 520 ) / 232440

= 447 / 520

= 447

Step2:

LCM(1, 140) = 140

GCD(1, 140) = ( 1 x 140 ) / 140

= 1 / 140

= 1

Step3:

LCM(1, 857) = 857

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

= 1 / 857

= 1

So, Greatest Common Divisor of 447, 520, 140, 857 is 1
