Given numbers are 880, 658, 406, 421

The list of prime factors of all numbers are

Prime factors of 880 are 2 x 2 x 2 x 2 x 5 x 11

Prime factors of 658 are 2 x 7 x 47

Prime factors of 406 are 2 x 7 x 29

Prime factors of 421 are 421

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

Given numbers are 880, 658, 406, 421

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

Apply this formula for all numbers.

Step1:

LCM(880, 658) = 289520

GCD(880, 658) = ( 880 x 658 ) / 289520

= 880 / 658

= 880

Step2:

LCM(2, 406) = 406

GCD(2, 406) = ( 2 x 406 ) / 406

= 2 / 406

= 2

Step3:

LCM(2, 421) = 842

GCD(2, 421) = ( 2 x 421 ) / 842

= 2 / 421

= 2

So, Greatest Common Divisor of 880, 658, 406, 421 is 1
