Given numbers are 831, 218, 915, 145

The list of prime factors of all numbers are

Prime factors of 831 are 3 x 277

Prime factors of 218 are 2 x 109

Prime factors of 915 are 3 x 5 x 61

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 831, 218, 915, 145

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

Apply this formula for all numbers.

Step1:

LCM(831, 218) = 181158

GCD(831, 218) = ( 831 x 218 ) / 181158

= 831 / 218

= 831

Step2:

LCM(1, 915) = 915

GCD(1, 915) = ( 1 x 915 ) / 915

= 1 / 915

= 1

Step3:

LCM(1, 145) = 145

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

= 1 / 145

= 1

So, Greatest Common Divisor of 831, 218, 915, 145 is 1
