Given numbers are 815, 378, 880, 145

The list of prime factors of all numbers are

Prime factors of 815 are 5 x 163

Prime factors of 378 are 2 x 3 x 3 x 3 x 7

Prime factors of 880 are 2 x 2 x 2 x 2 x 5 x 11

Prime factors of 145 are 5 x 29

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

Given numbers are 815, 378, 880, 145

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

Apply this formula for all numbers.

Step1:

LCM(815, 378) = 308070

GCD(815, 378) = ( 815 x 378 ) / 308070

= 815 / 378

= 815

Step2:

LCM(1, 880) = 880

GCD(1, 880) = ( 1 x 880 ) / 880

= 1 / 880

= 1

Step3:

LCM(1, 145) = 145

GCD(1, 145) = ( 1 x 145 ) / 145

= 1 / 145

= 1

So, Greatest Common Divisor of 815, 378, 880, 145 is 1
