Given numbers are 857, 631, 940, 945

The list of prime factors of all numbers are

Prime factors of 857 are 857

Prime factors of 631 are 631

Prime factors of 940 are 2 x 2 x 5 x 47

Prime factors of 945 are 3 x 3 x 3 x 5 x 7

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

Given numbers are 857, 631, 940, 945

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

Apply this formula for all numbers.

Step1:

LCM(857, 631) = 540767

GCD(857, 631) = ( 857 x 631 ) / 540767

= 857 / 631

= 857

Step2:

LCM(1, 940) = 940

GCD(1, 940) = ( 1 x 940 ) / 940

= 1 / 940

= 1

Step3:

LCM(1, 945) = 945

GCD(1, 945) = ( 1 x 945 ) / 945

= 1 / 945

= 1

So, Greatest Common Divisor of 857, 631, 940, 945 is 1
