What is the greatest common factor of 220 and 330?
The greatest common factor (GCF) of two numbers is the largest number that divides both numbers evenly. To find the GCF of 220 and 330, we first list the factors of each number: 220 (1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220) and 330 (1, 2, 3, 5, 6, 10, 11, 15, 22, 30, 33, 55, 66, 110, 165, 330). The common factors of 220 and 330 are 1, 2, 5, 10, 11, and 55. Therefore, the greatest common factor of 220 and 330 is 55.
Prime numbers between 180-220?
For this kind of question, I would suggest looking up a table of prime numbers. As an alternative, you can try to find factors for each of the numbers - if it has a factor, it is NOT a prime. For this range of numbers, testing for prime numbers up to 13 is appropriate. (If 17 is a factor of one of these numbers, the other factor is less than 17, so you would already have found it before you reach 17.)
What is 220 over 100 simplified?
To simplify 220/100, you can divide both the numerator and denominator by their greatest common factor (GCF). In this case, the GCF of 220 and 100 is 20. Dividing both numbers by 20 gives us 11/5. So, 220/100 simplified is 11/5.
What numbers are divisible by 220?
The multiples of 220 (which are infinite) are all divisible by 220, including these: 220, 440, 660, 880, 1100, 1320, 1540, 1760, 1980 . . .
What does 20 and 11 go into?
The numbers 20 and 11 can go into various larger numbers, but one common multiple they both divide evenly into is 220. This is because 220 is the least common multiple (LCM) of 20 and 11, as 220 is divisible by both numbers without leaving a remainder.
