What is the even number that is greater than 3 and is a factor of 20?
4 is greater than 3 and is a factor of 20.
Is the greatest common factor of two even numbers always even?
Assuming the second even number is equal to 4 or greater, than the highest common factor of the two numbers is equal to an even number 2 or greater. Why can't an odd factor be used? Any odd factor must be multiplied by (at least) 2 to create an even product (ie. the 1st even number). That same odd factor must be multiplied by (at least 2) and any other number to create a 2nd even product, thereby making the Greatest Common Factor (at least) 2 times the odd number....which is an even number.
What is the smalest prime factor of 144?
The smallest prime factor of any even number greater than two will always be two (2).
The greatest common factor of an odd number and an even number is 19 the greater number is 57 what is the other number?
38 is 2 x 19
Can an even number greater than 3 be prime?
No, a prime number has as its only two factors: one and itself. The number 2 satisfies this, but even numbers greater than three would have factors of one and itself, and also have 2 as a factor (because it's even) so then it's not prime.
What is the even number that is greater than 3 and is a factor of 20?
4 is greater than 3 and is a factor of 20.
Is the greater common factor of an odd number and an even number always even?
No, always odd.
What numbers have 2 as a factor and are composite?
Any even number greater than two.

What is an even number greater than 3 and is a factor of 20?
The factors of 20 are: 1,2,4,5,10,20 So; 4 and 10 are the even factors of 20 which are greater than 3.
What is the smalest prime factor of 144?
The smallest prime factor of any even number greater than two will always be two (2).
The greatest common factor of an odd number and an even number is 19 the greater number is 57 what is the other number?
38 is 2 x 19
What number has an even factor?
Any even number has at least one even factor.
Write this expression as a factorial 87654321?
That's not the factorial of any number. For a start, the factorial of any number greater than or equal to 2 is even, because of the factor 2. The factorial of any number greater or equal to five ends with 0. Another answer: I suspect the questioner meant to ask how to write 8*7*6*5*4*3*2*1 as a factorial. If so, then the answer is "8!"
Gcf odd and even number is 10 and the greater number is 57 what is the other number?
The GCF means it's a factor of both numbers. 10 is not a factor of 57.
How many even prime numbers are there and why?
There is only one even prime number, and that is 2. The reason is that all even numbers greater than 2 have 2 as a factor.
Is the Greatest common factor of a pair of numbers even greater than both numbers?
No, the greatest common factor is never greater than the smallest number. The greatest common factor is the largest integer that divides evenly into all of the numbers listed.
