Given numbers are 560, 862, 990, 605

The list of prime factors of all numbers are

Prime factors of 560 are 2 x 2 x 2 x 2 x 5 x 7

Prime factors of 862 are 2 x 431

Prime factors of 990 are 2 x 3 x 3 x 5 x 11

Prime factors of 605 are 5 x 11 x 11

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

Given numbers are 560, 862, 990, 605

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

Apply this formula for all numbers.

Step1:

LCM(560, 862) = 241360

GCD(560, 862) = ( 560 x 862 ) / 241360

= 560 / 862

= 560

Step2:

LCM(2, 990) = 990

GCD(2, 990) = ( 2 x 990 ) / 990

= 2 / 990

= 2

Step3:

LCM(2, 605) = 1210

GCD(2, 605) = ( 2 x 605 ) / 1210

= 2 / 605

= 2

So, Greatest Common Divisor of 560, 862, 990, 605 is 1
