Given numbers are 168, 144, 635, 945

The list of prime factors of all numbers are

Prime factors of 168 are 2 x 2 x 2 x 3 x 7

Prime factors of 144 are 2 x 2 x 2 x 2 x 3 x 3

Prime factors of 635 are 5 x 127

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 168, 144, 635, 945

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

Apply this formula for all numbers.

Step1:

LCM(168, 144) = 1008

GCD(168, 144) = ( 168 x 144 ) / 1008

= 168 / 144

= 168

Step2:

LCM(24, 635) = 15240

GCD(24, 635) = ( 24 x 635 ) / 15240

= 24 / 635

= 24

Step3:

LCM(1, 945) = 945

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

= 1 / 945

= 1

So, Greatest Common Divisor of 168, 144, 635, 945 is 1
