41 x 3 = 123, Quite basic actually.
No 5291 is not a prime using 2 numbers. It is a prime using three numbers.
I can find 13 ways, not just 7, to make 60 from adding numbers in the 4, 5 and 9 times tables.
They are: 2^4 times 3 times 5^2 times 7 = 8400
This week I learned my 4,5 and 6 times tables.
To factorise is to find the numbers that divide into the original number by only using prime numbers. For example factorise 20 = 2 times 2 times 5
To make 441 using four prime numbers, you can use the primes 3, 3, 7, and 7. When multiplied together, (3 \times 3 \times 7 \times 7) equals (9 \times 49), which is 441. Thus, the prime factorization is (3^2 \times 7^2 = 441).
Divide prime numbers into it. Start with 2. Do that four times. Then try 3. Stop.
3 x 5 x 11
Prime numbers have one factor pair, hence one rectangle.
To find the product of two numbers, simply multiply them using the multiplication operation. For example, if you want to find the product of 4 and 5, you calculate (4 \times 5), which equals 20. This can be done using a calculator, by hand, or using multiplication tables.
