Given numbers are 945, 684, 849, 287

The list of prime factors of all numbers are

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

Prime factors of 684 are 2 x 2 x 3 x 3 x 19

Prime factors of 849 are 3 x 283

Prime factors of 287 are 7 x 41

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

Given numbers are 945, 684, 849, 287

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

Apply this formula for all numbers.

Step1:

LCM(945, 684) = 71820

GCD(945, 684) = ( 945 x 684 ) / 71820

= 945 / 684

= 945

Step2:

LCM(9, 849) = 2547

GCD(9, 849) = ( 9 x 849 ) / 2547

= 9 / 849

= 9

Step3:

LCM(3, 287) = 861

GCD(3, 287) = ( 3 x 287 ) / 861

= 3 / 287

= 3

So, Greatest Common Divisor of 945, 684, 849, 287 is 1
