Given numbers are 690, 125, 434, 129

The list of prime factors of all numbers are

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

Prime factors of 125 are 5 x 5 x 5

Prime factors of 434 are 2 x 7 x 31

Prime factors of 129 are 3 x 43

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

Given numbers are 690, 125, 434, 129

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

Apply this formula for all numbers.

Step1:

LCM(690, 125) = 17250

GCD(690, 125) = ( 690 x 125 ) / 17250

= 690 / 125

= 690

Step2:

LCM(5, 434) = 2170

GCD(5, 434) = ( 5 x 434 ) / 2170

= 5 / 434

= 5

Step3:

LCM(1, 129) = 129

GCD(1, 129) = ( 1 x 129 ) / 129

= 1 / 129

= 1

So, Greatest Common Divisor of 690, 125, 434, 129 is 1
