Given numbers are 689, 102, 153, 454

The list of prime factors of all numbers are

Prime factors of 689 are 13 x 53

Prime factors of 102 are 2 x 3 x 17

Prime factors of 153 are 3 x 3 x 17

Prime factors of 454 are 2 x 227

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

Given numbers are 689, 102, 153, 454

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

Apply this formula for all numbers.

Step1:

LCM(689, 102) = 70278

GCD(689, 102) = ( 689 x 102 ) / 70278

= 689 / 102

= 689

Step2:

LCM(1, 153) = 153

GCD(1, 153) = ( 1 x 153 ) / 153

= 1 / 153

= 1

Step3:

LCM(1, 454) = 454

GCD(1, 454) = ( 1 x 454 ) / 454

= 1 / 454

= 1

So, Greatest Common Divisor of 689, 102, 153, 454 is 1
