WebSo, notice, now this number right over here has a 2 times 2 times 3 in it, or it has a 12 in it, and it has a 2 times 3 times 3, or an 18 in it. So this right over here is the least common multiple of 18 and 12. If we multiply it out, so 2 times 2 is 4. 4 times 3 is 12. 12 times 3 is equal to 36. And we are done. WebTherefore, the LCM is 224. Example 3: Find the greatest number that divides 28 and 32 exactly. Solution: The greatest number that divides 28 and 32 exactly is their greatest common factor, i.e. GCF of 28 and 32. ⇒ Factors of 28 and 32: Factors of 28 = 1, 2, 4, 7, 14, 28. Factors of 32 = 1, 2, 4, 8, 16, 32. Therefore, the GCF of 28 and 32 is 4.
WebDetailed Answer: The Greatest Common Factor (GCF) for 20 and 40, notation CGF (20,40), is 20. Explanation: The factors of 20 are 1,2,4,5,10,20; The factors of 40 are 1,2,4,5,8,10,20,40.
