Given numbers are 421,573,357

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

The LCM of 421,573,357 is 28706727.

Find LCM of 421,573,357 with Prime Factorization

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

3 x 421 x 191 x 119 = 28706727

Therefore, the lowest common multiple of 421,573,357 is 28706727.

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.

421 x 573 x 357 = 86120181

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.

421 : 1, 421

573 : 1, 3, 191, 573

357 : 1, 3, 7, 17, 21, 51, 119, 357

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 421,573,357, is 1.

Now, the common factors can be found like this.

421:421

573:3x 191

357:3x 7x 17

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 = 86120181/(1x3)

LCM = 86120181/3

LCM = 28706727

Thus, we can understand that the LCM of 421,573,357 is 28706727.

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

• LCM of 868, 218, 784
• LCM of 433, 642, 868
