Given numbers are 980, 990, 923, 401
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 990 are 2 x 3 x 3 x 5 x 11
Prime factors of 923 are 13 x 71
Prime factors of 401 are 401
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 980, 990, 923, 401
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(980, 990) = 97020
GCD(980, 990) = ( 980 x 990 ) / 97020
= 980 / 990
= 980
Step2:
LCM(10, 923) = 9230
GCD(10, 923) = ( 10 x 923 ) / 9230
= 10 / 923
= 10
Step3:
LCM(1, 401) = 401
GCD(1, 401) = ( 1 x 401 ) / 401
= 1 / 401
= 1
So, Greatest Common Divisor of 980, 990, 923, 401 is 1
