no if you multiply two primes for example 7x9=63 63 is not prime because 9 and 7 go into it
two prime numbers when added together will equal 63: 2 + 61
3*3*7=63
2 is a prime because it can only be multiplied by 1x6 but 63 isn't
No.

First you need to break the numbers into their prime factors. In this case we get: 63 = 3x3x7 21 = 3x7 The next step is to identify any common prime factors. In this case both have a 3 and a 7 as prime factors. Multiply these together and you get 3x7 = 21. This is the HCF. To find the LCM you just multiply the numbers together and divide by the HCF. 63x21/21 = 63 Thus 63 is the LCM.
7x9=63
47
61, 67, are prime numbers - 63 is not - 63 is a composite number.
Factors are numbers you can multiply together to get another number. A prime number can be divided evenly by 1 and itself. 63: 1, 3, 7, 9, 21, 63 The largest prime factor of 63 is 7.
To answer this question, you first need to break the number down into its prime factors: 63 = 3x3x7 To find two numbers that multiply to make 63, one number must be the product of some of these primes, and the other must be the product of the rest (you can also use 1). Thus the possible pairs are: 1x63 3x21 7x9

No.
73 is prime.
