Given numbers are 311, 616, 387, 145

The list of prime factors of all numbers are

Prime factors of 311 are 311

Prime factors of 616 are 2 x 2 x 2 x 7 x 11

Prime factors of 387 are 3 x 3 x 43

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 311, 616, 387, 145

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

Apply this formula for all numbers.

Step1:

LCM(311, 616) = 191576

GCD(311, 616) = ( 311 x 616 ) / 191576

= 311 / 616

= 311

Step2:

LCM(1, 387) = 387

GCD(1, 387) = ( 1 x 387 ) / 387

= 1 / 387

= 1

Step3:

LCM(1, 145) = 145

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

= 1 / 145

= 1

So, Greatest Common Divisor of 311, 616, 387, 145 is 1
