Procedure to Solve GCD of Numbers using the List of Factors method
Find the GCD of 48, 36, and 124 using a list of factors method?
Given numbers are 48, 36, 124
The common divisor from each set of factors is 1, 2, 4 and we see that the largest divisor is 4.
Thus, the Greatest Common Divisor of 48, 36, 124 is 4.
Steps to Solve Greatest Common Denominator or Divisor using Prime Factorization
Greatest common divisors can be calculated by determining the prime factorizations of the given numbers. Yes, prime factor decomposition is the most commonly used method to compute the GCD of given numbers. The steps comprised in computing the Greatest common divisor using prime factorization are as follows:
Solve the GCD of 16, 88, 104 by prime decomposition?
Given numbers are 16, 88, 104
Prime factors of 16 = 2 × 2 × 2 × 2
Prime factors of 88 = 2 × 2 × 2 × 11
Prime factors of 104 = 2 × 2 × 2 × 13
Now product the common prime factor and get the greatest common divisor
Thus, GCF(16, 88, 104) = 2 × 2 × 2 = 8.
How to Calculate GCD of two numbers by GCD Formula?
One more prominent method to calculate the GCD is by using the GCD formula. If a and b are both nonzero, the greatest common divisor of a and b can be calculated with the help of the least common multiple (lcm) of a and b:
GCD(a,b) = a×b / LCM(a,b)
Steps to solve Greatest Common Divisor Using GCD formula:
Find GCD of 23 and 45 using formula?
Given numbers are 23 and 45
The formula to find the greatest common divisor of two numbers is
GCD(a, b) = a x b / LCM(a, b)
GCD(23, 45) = 23*45 / LCM(23, 45)
GCD(23, 45) = 1035 / LCM(23, 45)
we get LCM of 23 and 45 is 1035 by applying primes
Now apply LCM(23, 45) in the formula and we get GCD of 23 and 45
GCD(23, 45) = 1035 / 1035
GCD(23, 45) = 1
Therefore, the greatest common divisor or greatest common denominator of 23 and 45 is 1.
