Given numbers are 890, 665, 686, 616

The list of prime factors of all numbers are

Prime factors of 890 are 2 x 5 x 89

Prime factors of 665 are 5 x 7 x 19

Prime factors of 686 are 2 x 7 x 7 x 7

Prime factors of 616 are 2 x 2 x 2 x 7 x 11

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

Given numbers are 890, 665, 686, 616

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

Apply this formula for all numbers.

Step1:

LCM(890, 665) = 118370

GCD(890, 665) = ( 890 x 665 ) / 118370

= 890 / 665

= 890

Step2:

LCM(5, 686) = 3430

GCD(5, 686) = ( 5 x 686 ) / 3430

= 5 / 686

= 5

Step3:

LCM(1, 616) = 616

GCD(1, 616) = ( 1 x 616 ) / 616

= 1 / 616

= 1

So, Greatest Common Divisor of 890, 665, 686, 616 is 1
