28 factors to [2 2 7] 36 factors to [2 2 3 3] Common factors are [2 2] Answer is 1, 2 and 4
The factors of 21 are: 1, 3, 7, 21.The factors of 36 are: 1, 2, 3, 4, 6, 9, 12, 18, 36.The common factors are: 1, 3
63 ... 3, 7, 9, 21, 63 36 ... 2, 3, 4, 6, 9, 12, 18, 36 common factors ... 3, 9
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.
Hint: 7 is a prime number, it has only 1 and itself as factors.The Greatest (and only) Common Factor (GCF) is: 1
To give a number in its simplest form, you need to identify any common divisors between the denominator and numerator. In this case, both 36 and 28 divide by 4. If we do this, we get 9/7. 9 and 7 have no common factors, and so 36/28 in its simplest form is 9/7.
Factors of 7: 1, 7Factors of 36: 1, 2, 3, 4, 6, 9, 12, 18, 36GCF (7, 36) = 1
The LCD is 36
The GCF of 28 and 36 is 4. One way to determine the greatest common factor is to find all the factors of the numbers and compare them. The factors of 28 are 1, 2, 4, 7, 14, and 28. The factors of 36 are 1, 2, 3, 4, 6, 9, 12, 18, and 36. The common factors are 1, 2, and 4. Therefore, the greatest common factor is 4. The greatest common factor can also be calculated by identifying the common prime factors and multiplying them together. The prime factors of 28 are 2, 2, and 7. The prime factors of 36 are 2, 2, 3, and 3. The prime factors in common are 2 and 2, so the greatest common factor is 2 x 2 = 4.
The common (note term) factors of 42 and 36 are 1,2,3, and 6.
Yes. 7 is a prime number, 36 not divisible by 7. In such cases, the GCF is 1.
