The list of prime factors of all numbers are

Prime factors of 675 are 3 x 3 x 3 x 5 x 5

Prime factors of 115 are 5 x 23

Prime factors of 830 are 2 x 5 x 83

Prime factors of 649 are 11 x 59

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

Given numbers are 675, 115, 830, 649

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

Apply this formula for all numbers.

Step1:

LCM(675, 115) = 15525

GCD(675, 115) = ( 675 x 115 ) / 15525

= 675 / 115

= 675

Step2:

LCM(5, 830) = 830

GCD(5, 830) = ( 5 x 830 ) / 830

= 5 / 830

= 5

Step3:

LCM(5, 649) = 3245

GCD(5, 649) = ( 5 x 649 ) / 3245

= 5 / 649

= 5

So, Greatest Common Divisor of 675, 115, 830, 649 is 1
