That's an infinite amount. Since numbers don't stop, factors don't either.
The GCF of 14, 26, and 42 is 2Divide them by a prime factor which goes into all numbers and carry on like this until you cannot divide the numbers by a same number.
2 x 3 x 3 x 7 = 126 2 x 2 x 3 x 7 x 7 = 588 2 x 3 x 7 = 42 42 is the largest (greatest) number that can go into both (common) numbers equally.
14, 28 and 42
Since 23 is a prime number, its only factors are 1 and itself. Since 42 is not divisible by 23, the greatest common factor is 1. Another way to determine the greatest common factor is to find all the factors of the numbers and compare them. The factors of 23 are 1 and 23. The factors of 42 are 1, 2, 3, 6, 7, 14, 21, and 42. The only common factor is 1. Therefore, the greatest common factor is 1, which means the numbers are relatively prime. The greatest common factor can also be calculated by identifying the common prime factors and multiplying them together. The prime factor of 23 is 23. The prime factors of 42 are 2, 3, and 7. There are no prime factors in common, so the numbers are relatively prime, meaning the greatest common factor is 1.
42 and 84 both qualify
21. GCF means what is the greatest number that goes into both, and 21*2=42.
The difference between a number and its reverse must be divisible by 9. 42 is NOT divisible by 9. There is, therefore, no such number.
Yes, the GCF of a # doesn't have to be either of the 2 #'s. In the case of 16 and 42 the GCF is 2 because that is the greatest # that both the numbers are equally divisible by. If it was 16 and 48, then the GCF would be 16 because that is the highest # both are equally divisible by.
A number that is divisible by both 3 and 7 must be a multiple of their least common multiple, which is 21. Therefore, any number that is a multiple of 21 will be divisible by both 3 and 7. Examples of such numbers include 21, 42, 63, 84, and so on.
Both are divisible by 6.
Yes, both.
42 is divisible by 2 (and other factors) so it is a composite number
42
42 and 49 are both divisible by 7. 42/49= 6/7
First, using your 2 divisibility rule, we find that both are even, therefore both are divisible by 2. Now, using the 3 divisibility rule, we know that 1 + 2 + 8 + 1 = 12, and 4 + 2 = 6, both multiples of 3. Thus, it must be divisible by 3 and 2, and it must divisible by 6! If so, then dividing both by 6 yields:1218/6 = 203, 42/6 = 7.Now both values are prime, therefore, 6 is the GCF of 1218 and 42.
The list is infinite. Here are some of them: 12, 18, 24, 30, 36, 42.
