Given numbers are 690, 500, 45, 579

The list of prime factors of all numbers are

Prime factors of 690 are 2 x 3 x 5 x 23

Prime factors of 500 are 2 x 2 x 5 x 5 x 5

Prime factors of 45 are 3 x 3 x 5

Prime factors of 579 are 3 x 193

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

Given numbers are 690, 500, 45, 579

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

Apply this formula for all numbers.

Step1:

LCM(690, 500) = 34500

GCD(690, 500) = ( 690 x 500 ) / 34500

= 690 / 500

= 690

Step2:

LCM(10, 45) = 90

GCD(10, 45) = ( 10 x 45 ) / 90

= 10 / 45

= 10

Step3:

LCM(5, 579) = 2895

GCD(5, 579) = ( 5 x 579 ) / 2895

= 5 / 579

= 5

So, Greatest Common Divisor of 690, 500, 45, 579 is 1
