Calculate the LCM of 221,450,222,404

Given numbers are 221,450,222,404

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

The LCM of 221,450,222,404 is 743289300.

Find LCM of 221,450,222,404 with Prime Factorization


2 221, 450, 222, 404
3 221, 225, 111, 202
221, 75, 37, 202

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

2 x 3 x 221 x 75 x 37 x 202 = 743289300

Therefore, the lowest common multiple of 221,450,222,404 is 743289300.

LCM Formula to Find Lowest Common Multiple of 221,450,222,404

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 450 x 222 x 404 = 8919471600

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

450 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 25, 30, 45, 50, 75, 90, 150, 225, 450

222 : 1, 2, 3, 6, 37, 74, 111, 222

404 : 1, 2, 4, 101, 202, 404

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 221,450,222,404, is 1.

Now, the common factors can be found like this.

221:13x 17

450:2x 3x 3x 5x 5

222:2x 3x 37

404:2x 2x 101

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

2x 2x 3 = 12

Therefore, the value for common factors is 12.

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 = 8919471600/(1x12)

LCM = 8919471600/12

LCM = 743289300

Thus, we can understand that the LCM of 221,450,222,404 is 743289300.
