Prime factors of 12 2x2x3 Prime factors of 36 2x2x3x3 Greatest common factor of 12 and 36 = 2x2x3 = 12
The prime factors of 24 are 2,2,2 and 3 The prime factors of 36 are 2,2,3 and 3 Thus the common factors are 1,2,3,4,6 and 12.
2 and 3
The prime factors of 24 are 2,2,2 and 3 The prime factors of 36 are 2,2,3 and 3 Thus the common factors are 1,2,3,4,6 and 12.
The prime factors of 36 are 2 and 3. To be common, they need to be compared to another set of prime factors.
The factors of 12 are: 1, 2, 3, 4, 6, and 12.The prime factors of 12 are: 2 and 3.The factors of 36 are: 1, 2, 3, 4, 6, 9, 12, 18, and 36.The prime factors of 36 are: 2 and 3.
Since 12 evenly divides into both 24 and 36, and is the largest factor of itself, 12 is the greatest common factor. Another way to determine the greatest common factor is to find all the factors of the numbers and compare them. The factors of 12 are 1, 2, 3, 4, 6, and 12. The factors of 24 are 1, 2, 3, 4, 6, 8, 12, and 24. The factors of 36 are 1, 2, 3, 4, 6, 9, 12, 18, and 36. The common factors are 1, 2, 3, 4, 6, and 12. Therefore, the greatest common factor is 12. The greatest common factor can also be calculated by identifying the common prime factors and multiplying them together. The prime factors of 12 are 2, 2, and 3. The prime factors of 24 are 2, 2, 2, and 3. The prime factors of 36 are 2, 2, 3, and 3. The prime factors in common are 2, 2, and 3, so the greatest common factor is 2 x 2 x 3 = 12.
The factors of 21 are 1, 3, 7, and 21. The factors of 36 are 1, 2, 3, 4, 6, 9, 12, 18, and 36. The factors they have in common are 1 and 3, the largest of which is 3, so 3 is the greatest common factor. Or, you can calculate the greatest common factor by looking at the prime factors. The prime factors of 21 are 3 and 7. The prime factors of 36 are 2, 2, 3, and 3. The prime factors they have in common are a single 3, so 3 is the greatest common factor.
The factors of 16 are 2, 4 and 8. The factors of 36 are 2, 4, 9, 12 and 18. The common factors are therefore 2 and 4. The common prime factor is 2.
Since 12 is a factor of 36, all of the factors of 12 are common to 36.
The LCM of 9 and 12 is: 36To determine the least common multiple of two numbers, determine the prime factors of both numbers. Then, determine the prime factors they have in common. Multiply all their prime factors together (in other words, multiply both numbers together) and divide by the prime factors they have in common (in other words, their greatest common factor).The prime factors of 9 are 3 and 3.The prime factors of 12 are 2, 2, and 3.The prime factors in common are a single 3, the greatest common factor is 3.36: 4 x 9, 3 x 12.The least common multiple of 12 , 9 = 36.3636
To find the highest common factor of two numbers you first have to split these numbers into their prime factors. In this case, 48 and 36 can be split up as follows: 48 = 2x2x2x2x3 36 = 2x2x3x3 The next step is to identify common prime factors. In this case, both numbers have two 2s as prime factors, and one 3. To find the highest common factor, you multiply these together: 2x2x3 = 12 Thus 12 is the highest common factor of 48 and 36.
