Given numbers are 840, 132, 403, 957

The list of prime factors of all numbers are

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

Prime factors of 132 are 2 x 2 x 3 x 11

Prime factors of 403 are 13 x 31

Prime factors of 957 are 3 x 11 x 29

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

Given numbers are 840, 132, 403, 957

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

Apply this formula for all numbers.

Step1:

LCM(840, 132) = 9240

GCD(840, 132) = ( 840 x 132 ) / 9240

= 840 / 132

= 840

Step2:

LCM(12, 403) = 4836

GCD(12, 403) = ( 12 x 403 ) / 4836

= 12 / 403

= 12

Step3:

LCM(1, 957) = 957

GCD(1, 957) = ( 1 x 957 ) / 957

= 1 / 957

= 1

So, Greatest Common Divisor of 840, 132, 403, 957 is 1
