Given numbers are 221,178,958

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

The LCM of 221,178,958 is 18842902.

Find LCM of 221,178,958 with Prime Factorization

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

2 x 221 x 89 x 479 = 18842902

Therefore, the lowest common multiple of 221,178,958 is 18842902.

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.

221 x 178 x 958 = 37685804

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.

221 : 1, 13, 17, 221

178 : 1, 2, 89, 178

958 : 1, 2, 479, 958

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 221,178,958, is 1.

Now, the common factors can be found like this.

221:13x 17

178:2x 89

958:2x 479

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

2 = 2

Therefore, the value for common factors is 2.

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 = 37685804/(1x2)

LCM = 37685804/2

LCM = 18842902

Thus, we can understand that the LCM of 221,178,958 is 18842902.

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

• LCM of 286, 903, 299
