Given numbers are 840, 275, 57, 943

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 275 are 5 x 5 x 11

Prime factors of 57 are 3 x 19

Prime factors of 943 are 23 x 41

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

Given numbers are 840, 275, 57, 943

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

Apply this formula for all numbers.

Step1:

LCM(840, 275) = 46200

GCD(840, 275) = ( 840 x 275 ) / 46200

= 840 / 275

= 840

Step2:

LCM(5, 57) = 285

GCD(5, 57) = ( 5 x 57 ) / 285

= 5 / 57

= 5

Step3:

LCM(1, 943) = 943

GCD(1, 943) = ( 1 x 943 ) / 943

= 1 / 943

= 1

So, Greatest Common Divisor of 840, 275, 57, 943 is 1
