GCD of numbers is the greatest common divisor
So, the GCD (19, 50, 20, 40) = 1.
Given numbers are 19, 50, 20, 40
The list of prime factors of all numbers are
Prime factors of 19 are 19
Prime factors of 50 are 2 x 5 x 5
Prime factors of 20 are 2 x 2 x 5
Prime factors of 40 are 2 x 2 x 2 x 5
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 19, 50, 20, 40
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(19, 50) = 950
GCD(19, 50) = ( 19 x 50 ) / 950
= 19 / 50
= 19
Step2:
LCM(1, 20) = 20
GCD(1, 20) = ( 1 x 20 ) / 20
= 1 / 20
= 1
Step3:
LCM(1, 40) = 40
GCD(1, 40) = ( 1 x 40 ) / 40
= 1 / 40
= 1
So, Greatest Common Divisor of 19, 50, 20, 40 is 1
