Both of those fractions are in their simplest form, which means they have a GCF of 1. The least common denominator is 20.
The prime factors of 180 are 2, 2, 3, 3, and 5. The prime factors of 216 are 2, 2, 2, 3, 3, and 3. The common factors are 2, 2, 3, and 3, so the greatest common factor is 2 x 2 x 3 x 3 = 36.
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 lowest common FACTOR of 7,3 and 2 is 42.
2, 3, 4 and 9 have only one common factor: 1
I usually start from the bottom - is 2 a factor, yes indeed. Then start over. Is 2 a factor, yes. Start over. Is 2 a factor, yes. Is 2 a factor, no. Is 3 a factor, no. is 4 a factor, no. Done.2, 2, 2, 5
one half, or 1 over 2 or 1/2 You find the greatest common factor in 3 and 6 and that is 3. Then you divide both by the greatest common factor then you get your answer 1/2
The common factor of 2 and 3 is: 1 The common factor of 3 and 4 is: 1 The common factors of 2 and 4 are: 1 and 2 The common factor or 2, 3 and 4 is: 1
2, leaving 3/8
2, leaving 3/8
Because 2 and 3 do not have a common factor other than one, it is reduced and in simplest form.
Yes, you can.4/6 can both be divided by a common factor: 2.If you divide both the numerator and denominator by 2, you get 2/3.You can't divide both 2 and 3 by a common factor, so 2/3 is the simplified form.
first factor both, and then eliminate the common factors. 36 factored is 2*2*3*3 48 factored is 2*2*2*2*3 they both have two "2"s in common and one "3" that can be eliminated, resulting in 3 over 2*2, or 3 over 4
The greatest common factor is 6 12= 2*2*3 42= 2*3*7 2*3= 6
common factor is 2 so 3/8
Take out a common factor of 3. 2/5.
The greatest common factor can be calculated by identifying the common prime factors and multiplying them together. The prime factors of 30 are 2, 3, and 5. The prime factors 1224 are 2, 2, 2, 3, 3, and 17. The prime factors in common are 2 and 3, so the greatest common factor is 2 x 3 = 6.
Since 6 is a factor of 48, and 6 is the largest factor of itself, 6 is the greatest common factor. One way to determine the greatest common factor is to find all the factors of the numbers and compare them. The factors of 6 are 1, 2, 3, and 6. The factors of 48 are 1, 2, 3, 4, 6, 8, 12, 16, 24, and 48. The common factors are 1, 2, 3, and 6. Therefore, 6 is the greatest common factor. The greatest common factor can also be calculated by identifying the common prime factors and multiplying them together. The prime factors of 6 are 2 and 3. The prime factors of 48 are 2, 2, 2, 2, and 3. The common prime factors are 2 and 3, so the greatest common factor is 2 x 3 = 6.
