Given numbers are 145, 310, 134, 815

The list of prime factors of all numbers are

Prime factors of 145 are 5 x 29

Prime factors of 310 are 2 x 5 x 31

Prime factors of 134 are 2 x 67

Prime factors of 815 are 5 x 163

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

Given numbers are 145, 310, 134, 815

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

Apply this formula for all numbers.

Step1:

LCM(145, 310) = 8990

GCD(145, 310) = ( 145 x 310 ) / 8990

= 145 / 310

= 145

Step2:

LCM(5, 134) = 670

GCD(5, 134) = ( 5 x 134 ) / 670

= 5 / 134

= 5

Step3:

LCM(1, 815) = 815

GCD(1, 815) = ( 1 x 815 ) / 815

= 1 / 815

= 1

So, Greatest Common Divisor of 145, 310, 134, 815 is 1
