Why is greatest common factor used?
Math is all about getting the most precise answer. You could reduce the fraction 8/12 to 4/6 but if you know that the GCF of 8 and 12 is 4, you can take 4 out of both of those and get 2/3, the simplest form. This makes a larger difference as numbers get larger.
What is the difference between the GCF and the LCM of 42 and 84?
Whenever one number is a multiple of the other, the LCM is the larger number and the GCF is the smaller number. The difference is 42.
What is the greatest common factor of 18 20 and 26?
The GCF of 18, 20, and 26 is 2. The GCF of a set of numbers can't be any larger than the smallest difference between the numbers. The smallest difference within this set of numbers is 2. Since all of the numbers in the set are even, 2 is the greatest common factor.
What Difference between the GCF and the LCM of 55 and 121?
605 - 11 = 594
What is a set of three numbers that have a GCF of 16?
16, 32 and 48 have a GCF of 16. Whether you added or multiplied to get them doesn't make much difference.
Can a gcf have more than one digit?
Of course! The reason you're getting single-digit gcf's so far is that the teacherneeds to keep it simple until you catch on and understand how to handle it.The gcf of 20 and 30 is 10.The gcf of 22 and 33 is 11.The gcf of 486 and 810 is 162.
What is the difference between gcf and the LCM of 55 and 121?
LCM 605 and GCF of 1. The difference is 604
What is the difference of the GCF and LCM of 24 and 120?
The GCF of 24 and 120 is 24. The LCM of 24 and 120 is 120. Therefore the difference between the GCF and LCM = 120 - 24 = 96
What is the gcf for 504 and 132?
Answer this by getting the prime factors of each number: 504= 2.2.2.3.3.7 132= 3.43 Just compare these lists. Since 132 is an oddball, having only two prime factors, the gcf is 3. Best wishes!

What Difference between the GCF and the LCM of 55 and 121?
605 - 11 = 594
What is the difference between the GCF and the LCM os 24 and 120?
120 - 24 = 96
What is the gcf of 100 375 and 400?
The difference between 375 and 400 is 25, so that is the largest possible value for the GCF. In fact, 100, 375, and 400 are all divisible by 25, so it is the GCF.
What is the GCF of two numbers whose sum is 24 and difference is 6?
The GCF of 9 and 15 is 3. The LCM is 45.
What is the greatest common factor of 16 18 and 30?
The GCF of 16, 18, and 30 is 2. The GCF of the set can't be any greater than the smallest difference between two numbers in the set. The difference between 16 and 18 is 2, and so that's the highest possible GCF. Noting that each number in the set is even, we then know that the GCF is, in fact, 2.The GCF is 2.
