WebOct 15, 2024 · 18. what is the gcf and lcm of 20 15 8 So the numbers you have are 20, 15 and 8 The Greatest Common Factor (GCF) is well... is the name itself We do the prime factorization of the numbers: [tex]20=2^2*5 \\ 15=3*5 \\ 8= 2^{3} [/tex] The GCF is 1 since the three don't have a common factor. WebFactoring reverses that process. You start by finding the largest common factor. For 21x + 56, the largest common factor (GCF) = 7. We factor it out by putting 7 in front and by dividing each term by 7. 21x + 56 = 7 (21x/7 + 56/7) = 7 (3x+8) Now, see if you can factor you expression. I'll get you started. your GCF = 7.

Gcf Of 18 And 24 - BRAINGITH - brainlyes.github.io

WebGCF of 18 and 24 is the divisor that we get when the remainder becomes 0 after doing long division repeatedly. Step 1: Divide 24 (larger number) by 18 (smaller number). Step 2: Since the remainder ≠ 0, we will divide the divisor of step 1 (18) by the remainder (6). Step 3: Repeat this process until the remainder = 0. WebOct 19, 2024 · 8 = 2 ⋅ 2 ⋅ 2. In fact, 8 only has one unique factor! If there is to be a common factor (other than 1) it must be 2. We now need to check that both 18 and 70 have 2 as a factor: 18 = 2 ⋅ 9. 70 = 2 ⋅ 35. Therefore, 2 is the GCF of 8, 18 and 70. Answer link. lawrence ks affordable housing
