Prime factors of 789 are 3 x 263
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 980, 456, 169, 789
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(980, 456) = 111720
GCD(980, 456) = ( 980 x 456 ) / 111720
= 980 / 456
= 980
Step2:
LCM(4, 169) = 676
GCD(4, 169) = ( 4 x 169 ) / 676
= 4 / 169
= 4
Step3:
LCM(1, 789) = 789
GCD(1, 789) = ( 1 x 789 ) / 789
= 1 / 789
= 1
So, Greatest Common Divisor of 980, 456, 169, 789 is 1
