As the word "common" might suggest, HCF is normally defined for two or more numbers, not just one. The highest "common" factor of a single number will be itself so the answer to the question is 315.
You need at least two numbers to find a GCF. If that's 3 and 15, the GCF is 3.
Steps to find out LCM of two numbers(a & b):1- Find HCF of a & b.2- Multiply a and b.3- Divide the result of step 2 by HCF. The result is LCM.1- In order to find out HCF of 540 and 315 we shall use the method of prime factorization.Prime factorization of 540 = 2x2x3x3x3x5Prime factorization of 315 = 3x3x5x7HCF(540, 315) = 3x3x5 = 45.2- Product of 540 and 315.540 x 315 = 170100.3- LCM(540, 315) = 170100/45 = 3780.
21% of 315= 21% * 315= 0.21 * 315= 66.15
HCF(10, 84) = 2 HCF(10, 84) = 2 HCF(10, 84) = 2 HCF(10, 84) = 2
315% = 3.15 315 = 31,500%
The HCF is: 2
The GCF is 45.
HCF(315, 195) = 15 LCM(315, 195) = 4095
21
The GCF is 21.
The GCF is 45.

The result is LCM.1- In order to find out HCF of 540 and 315 we shall use the method of prime factorization.Prime factorization of 540 = 2x2x3x3x3x5Prime factorization of 315 = 3x3x5x7HCF(540, 315) = 3x3x5 = 45.2- Product of 540 and 315.540 x 315 = 170100.3- LCM(540, 315) = 170100/45 = 3780.
The first step is to express these numbers as products of their prime factors: 315 = 3x3x5x7 660 = 2x2x3x5x11 The next step is to identify any common prime factors. In this case the common prime factors are 3 and 5. Multiply these and you get: 3x5 = 15 Thus the HCF of 315 and 660 is 15.
To have a HCF, you need at least 2 numbers. There is no HCF in just 1 number.

21% of 315= 21% * 315= 0.21 * 315= 66.15
The greatest common factor (GCF) is often also called the greatest common divisor (GCD) or highest common factor (HCF). Keep in mind that these different terms all refer to the same thing: the largest integer which evenly divides two or more numbers.The greatest common factor of 315 and 360 is 45
The LCM of 315 and 9 is 315
