Given numbers are 404, 100, 345, 654
The list of prime factors of all numbers are
Prime factors of 404 are 2 x 2 x 101
Prime factors of 100 are 2 x 2 x 5 x 5
Prime factors of 345 are 3 x 5 x 23
Prime factors of 654 are 2 x 3 x 109
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 404, 100, 345, 654
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(404, 100) = 10100
GCD(404, 100) = ( 404 x 100 ) / 10100
= 404 / 100
= 404
Step2:
LCM(4, 345) = 1380
GCD(4, 345) = ( 4 x 345 ) / 1380
= 4 / 345
= 4
Step3:
LCM(1, 654) = 654
GCD(1, 654) = ( 1 x 654 ) / 654
= 1 / 654
= 1
So, Greatest Common Divisor of 404, 100, 345, 654 is 1
