To find factors of -504 that add up to -3, we must consider both positive and negative factors. The factors of 504 are 1, 2, 3, 4, 6, 7, 8, 9, 12, 14, 18, 21, 24, 28, 36, 42, 56, 63, 72, 84, 126, 168, 252, and 504. By considering the negative factors as well, we can identify that -7 and -72 are factors of -504 that add up to -3.
To simplify a fraction you need to identify any common factors between the numerator and the denominator. In this case both 15 and 35 divide by 5. Do this and we get 3/7. There are no longer any common factors left. Thus the simplest form of the fraction 15/35 is 3/7.
1, 3, 7, 9, 21, 49, 63, 147, 441 3 and 7 are prime.
To find the Least Common Multiple (LCM) of 7, 3, and 21, we first need to identify the prime factors of each number. The prime factors of 7 are 7, of 3 are 3, and of 21 are 3 and 7. Then, we take the highest power of each prime factor that appears in any of the numbers. In this case, the LCM of 7, 3, and 21 is 21, as it includes the highest power of both 7 and 3.
1, -1, 3, -3, 7, -7, 21, -21 3 and 7 are prime.
To find the Highest Common Factor (HCF) of 42, 77, and 84, you first need to find the prime factors of each number. The prime factors of 42 are 2, 3, and 7. The prime factors of 77 are 7 and 11. The prime factors of 84 are 2, 3, and 7. To find the HCF, you need to identify the common prime factors and multiply them together. In this case, the HCF of 42, 77, and 84 is 7.
The factors of 21 are: 1 3 7 21 The prime factors are: 3 and 7
The factors of 63 are: 1 3 7 9 21 63. The prime factors are: 3 and 7
