The list of prime factors of all numbers are
Prime factors of 980 are 2 x 2 x 5 x 7 x 7
Prime factors of 573 are 3 x 191
Prime factors of 630 are 2 x 3 x 3 x 5 x 7
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 980, 573, 630, 555
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(980, 573) = 561540
GCD(980, 573) = ( 980 x 573 ) / 561540
= 980 / 573
= 980
Step2:
LCM(1, 630) = 630
GCD(1, 630) = ( 1 x 630 ) / 630
= 1 / 630
= 1
Step3:
LCM(1, 555) = 555
GCD(1, 555) = ( 1 x 555 ) / 555
= 1 / 555
= 1
So, Greatest Common Divisor of 980, 573, 630, 555 is 1
