Given numbers are 263,153,221,13

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 263,153,221,13 is 523107.

Find LCM of 263,153,221,13 with Prime Factorization

Multiply the prime numbers at the bottom and the left side.

13 x 17 x 263 x 9 x 1 x 1 = 523107

Therefore, the lowest common multiple of 263,153,221,13 is 523107.

LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

Firstly, we have to find the product of all the numbers.

263 x 153 x 221 x 13 = 115606647

Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.

263 : 1, 263

153 : 1, 3, 9, 17, 51, 153

221 : 1, 13, 17, 221

13 : 1, 13

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 263,153,221,13, is 1.

Now, the common factors can be found like this.

263:263

153:3x 3x 17

221:13x 17

13:13

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

13x 17 = 221

Therefore, the value for common factors is 221.

Now that we have all the elements of the formula, we can plug them in to calculate the LCM.

LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

LCM = 115606647/(1x221)

LCM = 115606647/221

LCM = 523107

Thus, we can understand that the LCM of 263,153,221,13 is 523107.

Here are some samples of LCM of two or more Numbers calculations.

• LCM of 129, 215, 347, 90
