Given numbers are 130, 665, 172, 755

The list of prime factors of all numbers are

Prime factors of 130 are 2 x 5 x 13

Prime factors of 665 are 5 x 7 x 19

Prime factors of 172 are 2 x 2 x 43

Prime factors of 755 are 5 x 151

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

Given numbers are 130, 665, 172, 755

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

Apply this formula for all numbers.

Step1:

LCM(130, 665) = 17290

GCD(130, 665) = ( 130 x 665 ) / 17290

= 130 / 665

= 130

Step2:

LCM(5, 172) = 860

GCD(5, 172) = ( 5 x 172 ) / 860

= 5 / 172

= 5

Step3:

LCM(1, 755) = 755

GCD(1, 755) = ( 1 x 755 ) / 755

= 1 / 755

= 1

So, Greatest Common Divisor of 130, 665, 172, 755 is 1
