Given numbers are 109,225,921,421

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

The LCM of 109,225,921,421 is 3169782675.

Find LCM of 109,225,921,421 with Prime Factorization

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

3 x 109 x 75 x 307 x 421 = 3169782675

Therefore, the lowest common multiple of 109,225,921,421 is 3169782675.

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.

109 x 225 x 921 x 421 = 9509348025

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.

109 : 1, 109

225 : 1, 3, 5, 9, 15, 25, 45, 75, 225

921 : 1, 3, 307, 921

421 : 1, 421

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 109,225,921,421, is 1.

Now, the common factors can be found like this.

109:109

225:3x 3x 5x 5

921:3x 307

421:421

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

3 = 3

Therefore, the value for common factors is 3.

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 = 9509348025/(1x3)

LCM = 9509348025/3

LCM = 3169782675

Thus, we can understand that the LCM of 109,225,921,421 is 3169782675.

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