The answer is. 5x3x3x3x3x3
35 times 5
3 x 3 x 3 x 3 x 3 x 5 = 1215
35 x 5 = 1215
To find the highest common factor (HCF) of 81, 243, and 1215, we first need to find the prime factorization of each number. The prime factorization of 81 is 3^4, 243 is 3^5, and 1215 is 3^5 * 5. To find the HCF, we look for the highest power of each prime factor that appears in all the numbers. In this case, the highest power of 3 that appears in all three numbers is 3^4, so the HCF of 81, 243, and 1215 is 81.
To find fractions equivalent to 1215, we need to divide 1215 by a common factor. The prime factorization of 1215 is 3 x 3 x 3 x 3 x 3 x 3 x 5. So, any fraction where both the numerator and denominator are multiples of these prime factors will be equivalent to 1215. For example, 2430/2, 405/3, and 135/5 are all equivalent fractions to 1215.
The least common multiple (LCM) is often also called the lowest common multiple or smallest common multiple. Keep in mind that these different terms all refer to the same thing: the smallest positive integer which is a multiple of two or more numbers.The least common multiple of 243 and 405 is 1215.
1215 is divisible by 3 because its digits add up to a multiple of 3. That leaves 405. 405 is divisible by 3, leaving 135. 135 is divisible by 3, leaving 45. 45 is divisible by 3, leaving 15. 15 is divisible by 3, leaving 5. 5 is divisible by 5 because it ends in 5. 3 x 3 x 3 x 3 x 3 x 5 = 1215
June 15, 1215 was a Monday if they were using the Gregorian calendar back then.
