Given numbers are 651, 260, 289, 690

The list of prime factors of all numbers are

Prime factors of 651 are 3 x 7 x 31

Prime factors of 260 are 2 x 2 x 5 x 13

Prime factors of 289 are 17 x 17

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

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

Given numbers are 651, 260, 289, 690

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

Apply this formula for all numbers.

Step1:

LCM(651, 260) = 169260

GCD(651, 260) = ( 651 x 260 ) / 169260

= 651 / 260

= 651

Step2:

LCM(1, 289) = 289

GCD(1, 289) = ( 1 x 289 ) / 289

= 1 / 289

= 1

Step3:

LCM(1, 690) = 690

GCD(1, 690) = ( 1 x 690 ) / 690

= 1 / 690

= 1

So, Greatest Common Divisor of 651, 260, 289, 690 is 1
