Given numbers are 820, 458, 955, 689

The list of prime factors of all numbers are

Prime factors of 820 are 2 x 2 x 5 x 41

Prime factors of 458 are 2 x 229

Prime factors of 955 are 5 x 191

Prime factors of 689 are 13 x 53

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

Given numbers are 820, 458, 955, 689

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

Apply this formula for all numbers.

Step1:

LCM(820, 458) = 187780

GCD(820, 458) = ( 820 x 458 ) / 187780

= 820 / 458

= 820

Step2:

LCM(2, 955) = 1910

GCD(2, 955) = ( 2 x 955 ) / 1910

= 2 / 955

= 2

Step3:

LCM(1, 689) = 689

GCD(1, 689) = ( 1 x 689 ) / 689

= 1 / 689

= 1

So, Greatest Common Divisor of 820, 458, 955, 689 is 1
