Given numbers are 990, 134, 405, 181
The list of prime factors of all numbers are
Prime factors of 990 are 2 x 3 x 3 x 5 x 11
Prime factors of 134 are 2 x 67
Prime factors of 405 are 3 x 3 x 3 x 3 x 5
Prime factors of 181 are 181
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 990, 134, 405, 181
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(990, 134) = 66330
GCD(990, 134) = ( 990 x 134 ) / 66330
= 990 / 134
= 990
Step2:
LCM(2, 405) = 810
GCD(2, 405) = ( 2 x 405 ) / 810
= 2 / 405
= 2
Step3:
LCM(1, 181) = 181
GCD(1, 181) = ( 1 x 181 ) / 181
= 1 / 181
= 1
So, Greatest Common Divisor of 990, 134, 405, 181 is 1
