Factors that end with zero: Factors whose unit digit is zero or we can say factors which are divisible by 10. Example 1: Find the number of factors of 58800 that end with 0. Solution: If a number ends with 0 then it must have at least 21 and 51. We first factorize... by Wordpandit | May 6, 2015 | Mathematics Concepts, Number System Concepts |
Various Types of Factors Even factors: Even factors are the factors of number, which are divisible by 2. Example 1: Find the number of even factors of 58800? Solution: We first factorize 58800. 58800 = 24 315272 In this case we have to find number of even factors, an... by Wordpandit | May 6, 2015 | Mathematics Concepts, Number System Concepts |
Shortcut for LCM Type 1: Remainder is same when divided by distinct divisors If the Number N leaves the same remainder R when divided by the numbers a, b, c, then the number N = (LCM of (a, b, c) p +R, where p is any whole number. Type 2: Difference between the... by Wordpandit | May 6, 2015 | Mathematics Concepts, Number System Concepts |
H.C.F. by Long Division Method To find the H.C.F. of the given number we will follow the following steps: We divide the bigger number by smaller one. Divide smaller number in step 1 with remainder obtained in step 1. Divide divisor of second step with remainder...
