Given numbers are 400, 297, 80, 979

The list of prime factors of all numbers are

Prime factors of 400 are 2 x 2 x 2 x 2 x 5 x 5

Prime factors of 297 are 3 x 3 x 3 x 11

Prime factors of 80 are 2 x 2 x 2 x 2 x 5

Prime factors of 979 are 11 x 89

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

Given numbers are 400, 297, 80, 979

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

Apply this formula for all numbers.

Step1:

LCM(400, 297) = 118800

GCD(400, 297) = ( 400 x 297 ) / 118800

= 400 / 297

= 400

Step2:

LCM(1, 80) = 80

GCD(1, 80) = ( 1 x 80 ) / 80

= 1 / 80

= 1

Step3:

LCM(1, 979) = 979

GCD(1, 979) = ( 1 x 979 ) / 979

= 1 / 979

= 1

So, Greatest Common Divisor of 400, 297, 80, 979 is 1
