Given numbers are 298, 546, 445, 980

The list of prime factors of all numbers are

Prime factors of 298 are 2 x 149

Prime factors of 546 are 2 x 3 x 7 x 13

Prime factors of 445 are 5 x 89

Prime factors of 980 are 2 x 2 x 5 x 7 x 7

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

Given numbers are 298, 546, 445, 980

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

Apply this formula for all numbers.

Step1:

LCM(298, 546) = 81354

GCD(298, 546) = ( 298 x 546 ) / 81354

= 298 / 546

= 298

Step2:

LCM(2, 445) = 890

GCD(2, 445) = ( 2 x 445 ) / 890

= 2 / 445

= 2

Step3:

LCM(1, 980) = 980

GCD(1, 980) = ( 1 x 980 ) / 980

= 1 / 980

= 1

So, Greatest Common Divisor of 298, 546, 445, 980 is 1
