Given numbers are 403, 612, 821, 718

The list of prime factors of all numbers are

Prime factors of 403 are 13 x 31

Prime factors of 612 are 2 x 2 x 3 x 3 x 17

Prime factors of 821 are 821

Prime factors of 718 are 2 x 359

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

Given numbers are 403, 612, 821, 718

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

Apply this formula for all numbers.

Step1:

LCM(403, 612) = 246636

GCD(403, 612) = ( 403 x 612 ) / 246636

= 403 / 612

= 403

Step2:

LCM(1, 821) = 821

GCD(1, 821) = ( 1 x 821 ) / 821

= 1 / 821

= 1

Step3:

LCM(1, 718) = 718

GCD(1, 718) = ( 1 x 718 ) / 718

= 1 / 718

= 1

So, Greatest Common Divisor of 403, 612, 821, 718 is 1
