Given numbers are 690, 909, 987, 566

The list of prime factors of all numbers are

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

Prime factors of 909 are 3 x 3 x 101

Prime factors of 987 are 3 x 7 x 47

Prime factors of 566 are 2 x 283

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

Given numbers are 690, 909, 987, 566

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

Apply this formula for all numbers.

Step1:

LCM(690, 909) = 209070

GCD(690, 909) = ( 690 x 909 ) / 209070

= 690 / 909

= 690

Step2:

LCM(3, 987) = 987

GCD(3, 987) = ( 3 x 987 ) / 987

= 3 / 987

= 3

Step3:

LCM(3, 566) = 1698

GCD(3, 566) = ( 3 x 566 ) / 1698

= 3 / 566

= 3

So, Greatest Common Divisor of 690, 909, 987, 566 is 1
