If you were to find the GCF of 20 and 36. Draw 2 overlapping circles. List "20" above one of the circles and "36" above the other. In the circle under "20", list the factors of 20 that are NOT factors of 36- 1, 5, 10, 20. In the other circle, list the factors of 36 that are NOT factors of 20- 1, 3, 6, 9, 12, 36. The factors that 20 and 36 that are in common are listed in the overlapping part of the circle or intersection- 2, 4. The greatest number in common is 4 (GCF). In other words, the largest number listed in the intersection is the GCF.

Intersection and union of sets of real numbers?
Yes, they can be very useful mathematical sets.
What is the intersection set?
is the result after doing intersection on 2 or more sets. It contains the elements which are common to all the sets on which intersection were done.
Do the intersection of two sets always contains a smaller number of terms than the union of two sets?
No, because the intersection of two equivalent sets will have a union the same size as its intersection.
How do you illustrate a joint sets by using a venn diagram?
Disjoint sets are sets whose intersection, denoted by an inverted U), produces the null or the empty set. If a set is not disjoint, then it is called joint. [ex. M= {1,2,A} N = {4,5,B}. S intersection D is a null set, so M and N are disjoint sets.
What is the meaning of intersection of two sets?
The intersection of two sets S and T is the set of all elements that belong to both S and T.
Intersection and union of sets of real numbers?
Yes, they can be very useful mathematical sets.
Can some numbers be rational and irrational?
No. The intersection of the two sets is null. Irrational numbers are defined as real numbers that are NOT rational.

What does intersection mean in math?
It means meet. Point of intersection is the point where shapes or lines meet. With regard to sets, the intersection of two sets is the set of elements that are common to both sets. For example, the intersection of the set of the first five whole numbers and the set of the first five odd numbers is the set of the first three odd numbers. This is expressed as {1, 2, 3, 4, 5} ∩ {1, 3, 5, 7, 9} = {1, 3, 5}
Is intersection of two countably infinite sets can be finite?
Easily. Indeed, it might be empty. Consider the set of positive odd numbers, and the set of positive even numbers. Both are countably infinite, but their intersection is the empty set. For a non-empty intersection, consider the set of positive odd numbers, and 2, and the set of positive even numbers. Both are still countably infinite, but their intersection is {2}.
The intersection of two sets of elements is represented by the word?
the intersection of two sets of elements is represented by the word: a)or b)and c)up
What is intersection of the set?
You normally do not have an intersection of only one set. The intersection of a set with itself is the set itself - a statement that adds little value. The intersection of two sets is the set which contains elements that are in each of the two sets.
How do you illustrate a joint sets by using a venn diagram?
Disjoint sets are sets whose intersection, denoted by an inverted U), produces the null or the empty set. If a set is not disjoint, then it is called joint. [ex. M= {1,2,A} N = {4,5,B}. S intersection D is a null set, so M and N are disjoint sets.
How do you compare integers with positive numbers?
Some integers are positive numbers.Some integers are not positive numbers.Some positive numbers are integers.Some positive numbers are not integers.They are two sets whose intersection is the set of counting numbers.
What is the meaning of intersection of two sets?
The intersection of two sets S and T is the set of all elements that belong to both S and T.
Do sets always have an intersection that is not the empty set?
No, they do not.
