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).
2 + 3 + 5 + 431 = 441
3 x 3 x 7 x 7
3 x 3 x 7 x 7 = 441
To find four numbers that multiply to make 441, you can break 441 down into its prime factors, which are 3, 3, 7, and 7 (since (441 = 3^2 \times 7^2)). A possible set of four numbers could be 1, 3, 7, and 21, since (1 \times 3 \times 7 \times 21 = 441). Other combinations are also possible, depending on how you choose to group the factors.
To find the prime factors of a number, you should start by dividing it by any obvious divisors. In this case, the digit sum of 441 is 9, and so we know that it can divide by 9. Do this and we get 49, which is known from times tables to be 7x7. 9 can be broken down into 3x3. Thus the number 441 can be expressed as 3x3x7x7.
2 + 3 + 5 + 431 = 441
3 x 3 x 7 x 7 = 441
3 x 3 x 7 x 7
3 x 3 x 7 x 7 = 441
