Given numbers are 308, 690, 433, 655

The list of prime factors of all numbers are

Prime factors of 308 are 2 x 2 x 7 x 11

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

Prime factors of 433 are 433

Prime factors of 655 are 5 x 131

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

Given numbers are 308, 690, 433, 655

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

Apply this formula for all numbers.

Step1:

LCM(308, 690) = 106260

GCD(308, 690) = ( 308 x 690 ) / 106260

= 308 / 690

= 308

Step2:

LCM(2, 433) = 866

GCD(2, 433) = ( 2 x 433 ) / 866

= 2 / 433

= 2

Step3:

LCM(1, 655) = 655

GCD(1, 655) = ( 1 x 655 ) / 655

= 1 / 655

= 1

So, Greatest Common Divisor of 308, 690, 433, 655 is 1
