GCD of numbers is the greatest common divisor
So, the GCD (25, 33, 56, 15) = 1.
Given numbers are 25, 33, 56, 15
The list of prime factors of all numbers are
Prime factors of 25 are 5 x 5
Prime factors of 33 are 3 x 11
Prime factors of 56 are 2 x 2 x 2 x 7
Prime factors of 15 are 3 x 5
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 25, 33, 56, 15
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(25, 33) = 825
GCD(25, 33) = ( 25 x 33 ) / 825
= 25 / 33
= 25
Step2:
LCM(1, 56) = 56
GCD(1, 56) = ( 1 x 56 ) / 56
= 1 / 56
= 1
Step3:
LCM(1, 15) = 15
GCD(1, 15) = ( 1 x 15 ) / 15
= 1 / 15
= 1
So, Greatest Common Divisor of 25, 33, 56, 15 is 1
