The prime factorization of 14 is 2 x 7.
The easiest way to do this is to split the numbers down into their prime factors: 14 = 2x7 20 = 2x2x5 The next step is to spot any common prime factors. In this case both numbers have a 2 as a prime factor. Therefore, the HCF of 14 and 20 is 2.
A multiple of 7 is any number that can divide evenly into 7. The easy way to find multiples of 7 is to multiply 7 by each integer in turn (1x7, 2x7, 3x7, 4x7, and so on). Using this method, you can quickly work out what the multiples of 7 between 15 and 50 are. They are: 21, 28, 35, 42 and 49.
Any numbers that don't have common prime factors will do; for example, 23 and 32; 2x3 and 5x7, 3x5 and 2x7, etc.Any two consecutive numbers will have no common factor, for example, 8 and 9 (the first example I gave above), or 100 and 101. However, in the second example, 101 is not a composite number.
The GCF of 14 and 17 is 1. Since 17 is prime, their GCF must be 1.The factors of 14 are 1, 2, 7 and 14The factors of 17 are 1 and 17.So, the GCF = 1.Alternate method:Method of prime factorization14 = 2x7 and 17 = 17It is clear from the prime factorization of both numbers that there is no common factor except 1.Therefore, greatest common factor of 14 and 17 is 1.The GCF is 1.
The final answer is 112.
2 x 7 + 5 = 19
I'm going to assume the polynomial in question is 2x7+(3-2x3)+(5x8-4x) Expanding out the polynomial: 2x7+3-2x3+5x8-4x Order the terms by powers of x: 5x8+2x7-2x3-4x+3 Since 8 is the highest power of x, the degree of the polynomial is 8.
If I do your homework for you, you will fail your test.
19 - 2*7 + 98/14 = 12.
2 4/7 = (2x7+4)/7 = 18/7
The LCM (Least Common Multiple) of 2x7 and 4x9 is 36x63.
