Given numbers are 821, 659, 730, 912

The list of prime factors of all numbers are

Prime factors of 821 are 821

Prime factors of 659 are 659

Prime factors of 730 are 2 x 5 x 73

Prime factors of 912 are 2 x 2 x 2 x 2 x 3 x 19

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

Given numbers are 821, 659, 730, 912

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

Apply this formula for all numbers.

Step1:

LCM(821, 659) = 541039

GCD(821, 659) = ( 821 x 659 ) / 541039

= 821 / 659

= 821

Step2:

LCM(1, 730) = 730

GCD(1, 730) = ( 1 x 730 ) / 730

= 1 / 730

= 1

Step3:

LCM(1, 912) = 912

GCD(1, 912) = ( 1 x 912 ) / 912

= 1 / 912

= 1

So, Greatest Common Divisor of 821, 659, 730, 912 is 1
