Given numbers are 945, 130, 455, 647

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 130 are 2 x 5 x 13

Prime factors of 455 are 5 x 7 x 13

Prime factors of 647 are 647

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

Given numbers are 945, 130, 455, 647

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

Apply this formula for all numbers.

Step1:

LCM(945, 130) = 24570

GCD(945, 130) = ( 945 x 130 ) / 24570

= 945 / 130

= 945

Step2:

LCM(5, 455) = 455

GCD(5, 455) = ( 5 x 455 ) / 455

= 5 / 455

= 5

Step3:

LCM(5, 647) = 3235

GCD(5, 647) = ( 5 x 647 ) / 3235

= 5 / 647

= 5

So, Greatest Common Divisor of 945, 130, 455, 647 is 1
