Given numbers are 180, 418, 521, 394
The list of prime factors of all numbers are
Prime factors of 180 are 2 x 2 x 3 x 3 x 5
Prime factors of 418 are 2 x 11 x 19
Prime factors of 521 are 521
Prime factors of 394 are 2 x 197
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 180, 418, 521, 394
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(180, 418) = 37620
GCD(180, 418) = ( 180 x 418 ) / 37620
= 180 / 418
= 180
Step2:
LCM(2, 521) = 1042
GCD(2, 521) = ( 2 x 521 ) / 1042
= 2 / 521
= 2
Step3:
LCM(1, 394) = 394
GCD(1, 394) = ( 1 x 394 ) / 394
= 1 / 394
= 1
So, Greatest Common Divisor of 180, 418, 521, 394 is 1
