Given numbers are 130, 786, 155, 465

The list of prime factors of all numbers are

Prime factors of 130 are 2 x 5 x 13

Prime factors of 786 are 2 x 3 x 131

Prime factors of 155 are 5 x 31

Prime factors of 465 are 3 x 5 x 31

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

Given numbers are 130, 786, 155, 465

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

Apply this formula for all numbers.

Step1:

LCM(130, 786) = 51090

GCD(130, 786) = ( 130 x 786 ) / 51090

= 130 / 786

= 130

Step2:

LCM(2, 155) = 310

GCD(2, 155) = ( 2 x 155 ) / 310

= 2 / 155

= 2

Step3:

LCM(1, 465) = 465

GCD(1, 465) = ( 1 x 465 ) / 465

= 1 / 465

= 1

So, Greatest Common Divisor of 130, 786, 155, 465 is 1
