Given numbers are 830, 978, 906, 555

The list of prime factors of all numbers are

Prime factors of 830 are 2 x 5 x 83

Prime factors of 978 are 2 x 3 x 163

Prime factors of 906 are 2 x 3 x 151

Prime factors of 555 are 3 x 5 x 37

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

Given numbers are 830, 978, 906, 555

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

Apply this formula for all numbers.

Step1:

LCM(830, 978) = 405870

GCD(830, 978) = ( 830 x 978 ) / 405870

= 830 / 978

= 830

Step2:

LCM(2, 906) = 906

GCD(2, 906) = ( 2 x 906 ) / 906

= 2 / 906

= 2

Step3:

LCM(2, 555) = 1110

GCD(2, 555) = ( 2 x 555 ) / 1110

= 2 / 555

= 2

So, Greatest Common Divisor of 830, 978, 906, 555 is 1
