Given numbers are 891, 658, 580, 485

The list of prime factors of all numbers are

Prime factors of 891 are 3 x 3 x 3 x 3 x 11

Prime factors of 658 are 2 x 7 x 47

Prime factors of 580 are 2 x 2 x 5 x 29

Prime factors of 485 are 5 x 97

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

Given numbers are 891, 658, 580, 485

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

Apply this formula for all numbers.

Step1:

LCM(891, 658) = 586278

GCD(891, 658) = ( 891 x 658 ) / 586278

= 891 / 658

= 891

Step2:

LCM(1, 580) = 580

GCD(1, 580) = ( 1 x 580 ) / 580

= 1 / 580

= 1

Step3:

LCM(1, 485) = 485

GCD(1, 485) = ( 1 x 485 ) / 485

= 1 / 485

= 1

So, Greatest Common Divisor of 891, 658, 580, 485 is 1
