Given numbers are 890, 798, 564, 921

The list of prime factors of all numbers are

Prime factors of 890 are 2 x 5 x 89

Prime factors of 798 are 2 x 3 x 7 x 19

Prime factors of 564 are 2 x 2 x 3 x 47

Prime factors of 921 are 3 x 307

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

Given numbers are 890, 798, 564, 921

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

Apply this formula for all numbers.

Step1:

LCM(890, 798) = 355110

GCD(890, 798) = ( 890 x 798 ) / 355110

= 890 / 798

= 890

Step2:

LCM(2, 564) = 564

GCD(2, 564) = ( 2 x 564 ) / 564

= 2 / 564

= 2

Step3:

LCM(2, 921) = 1842

GCD(2, 921) = ( 2 x 921 ) / 1842

= 2 / 921

= 2

So, Greatest Common Divisor of 890, 798, 564, 921 is 1
