WebThe second method to find GCF for numbers 8 and 16 is to list all Prime Factors for both numbers and multiply the common ones: All Prime Factors of 8: 2, 2, 2. All Prime Factors of 16: 2, 2, 2, 2. As we can see there are Prime Factors common to both numbers: 2, 2, 2. Now we need to multiply them to find GCF: 2 × 2 × 2 = 8. WebPrime Factors for 16: 2, 2, 2, and 2. Prime Factors for 18: 2, 3, and 3. Now that we have the list of prime factors, we need to find any which are common for each number. In this case, there is only one common prime factor, 2. Since there are no others, the greatest common factor is this prime factor: GCF = 2.
Greatest Common Factor and Least Common Multiple
WebFor smaller numbers you can simply look at the factors or multiples for each number and find the greatest common multiple of them. For 8 and 16 those factors look like this: Factors for 8: 1, 2, 4, and 8. Factors for 16: 1, 2, 4, 8, and 16. As you can see when you list out the factors of each number, 8 is the greatest number that 8 and 16 ... WebWhat is the Greatest Common Factor of 8 and 16?
