What is the HCF of 32 and 98?
To work this out, you have to split the numbers into their prime factors: 32 = 2x2x2x2x2 98 = 2x7x7 The next step is to spot any common prime factors. In this case both numbers have a 2 as a prime factors. Thus the HCF of 32 and 98 is 2.
What is the HCF of 14 and 20?
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.
If you roll two standard dice what is the probability that the sum of their spot values will be a prime number?

What is the HCF of 4 8?
To work this out, you need to break each number into its prime factors: 4 = 2x2 8 = 2x2x2 The next step is to spot any common prime factors. In this case both numbers have two 2s as prime factors. Multiply these together and you get: 2x2 = 4 Therefore the HCF of 4 and 8 is 4.
Is 940 a prime number?
No.Two reasons that are easy to spot:940 is an even number and the only even prime number is 2;the last digit of 940 is 0 and so it is divisible by 10.The prime factorization of 940 is 2 x 2 x 5 x 47
What two prime numbers added together make a square number?
The only two prime numbers that can be added together to make a square number are 2 and 2. When you add them together, you get 4, which is a square number (2 x 2 = 4). This is because all other prime numbers, when added together, will result in an even sum that is not a square number.
What is the GCF of 48 and 56!?
To get the gcf of 56 and 48, you have to split the numbers into their prime factors: 56 = 2x2x2x7 48 = 2x2x2x2x3 Next you have to spot any common prime factors. In this case both numbers have three 2s as prime factors. Multiply these together and you get: 2x2x2 = 8 And so the GCF of 56 and 48 is 8.

What does stem and leaf plot mean in math?
This is an example. A stem and leaf plot is a plot where numbers with more than two digits are broken down into parts. The numbers in the "tens" spot is put on the left side of the vertical line. The numbers in the "ones" spot is on the right of the vertical line. For instance, on the top of the chart, there is a 9. On the other side of the line, there is a zero. Therefore, it represents "90". Beside the zero, there is a 4. So the next number would be "94". The chart is basically used to organize and graph larger numbers.
Is 2100 prime or composite?
A prime number is one who's only factors are One and Itself. Sometimes people will say a number is 'divisible by X', which means that X is a factor of the number. There are several tests for certain factors that you can do quickly, if you memorize them. For example, 2100 has several factors that I can spot without doing any division: It has zero in the ones digit. This tells me that it's divisible by 5, also 0 in ones digit tells me that it's even (divisible by 2). The 'sum of the digits' is a multiple of three, so the number is also a multiple of three (2 + 1 + 0 + 0 = 3).
