Given numbers are 421, 912, 770, 581

The list of prime factors of all numbers are

Prime factors of 421 are 421

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

Prime factors of 770 are 2 x 5 x 7 x 11

Prime factors of 581 are 7 x 83

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

Given numbers are 421, 912, 770, 581

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

Apply this formula for all numbers.

Step1:

LCM(421, 912) = 383952

GCD(421, 912) = ( 421 x 912 ) / 383952

= 421 / 912

= 421

Step2:

LCM(1, 770) = 770

GCD(1, 770) = ( 1 x 770 ) / 770

= 1 / 770

= 1

Step3:

LCM(1, 581) = 581

GCD(1, 581) = ( 1 x 581 ) / 581

= 1 / 581

= 1

So, Greatest Common Divisor of 421, 912, 770, 581 is 1
