Given numbers are 690, 654, 750, 289

The list of prime factors of all numbers are

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

Prime factors of 654 are 2 x 3 x 109

Prime factors of 750 are 2 x 3 x 5 x 5 x 5

Prime factors of 289 are 17 x 17

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

Given numbers are 690, 654, 750, 289

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

Apply this formula for all numbers.

Step1:

LCM(690, 654) = 75210

GCD(690, 654) = ( 690 x 654 ) / 75210

= 690 / 654

= 690

Step2:

LCM(6, 750) = 750

GCD(6, 750) = ( 6 x 750 ) / 750

= 6 / 750

= 6

Step3:

LCM(6, 289) = 1734

GCD(6, 289) = ( 6 x 289 ) / 1734

= 6 / 289

= 6

So, Greatest Common Divisor of 690, 654, 750, 289 is 1
