Given numbers are 916,842,421

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

The LCM of 916,842,421 is 385636.

Find LCM of 916,842,421 with Prime Factorization

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

2 x 421 x 458 x 1 x 1 = 385636

Therefore, the lowest common multiple of 916,842,421 is 385636.

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.

916 x 842 x 421 = 324705512

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.

916 : 1, 2, 4, 229, 458, 916

842 : 1, 2, 421, 842

421 : 1, 421

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 916,842,421, is 1.

Now, the common factors can be found like this.

916:2x 2x 229

842:2x 421

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.

2x 421 = 842

Therefore, the value for common factors is 842.

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 = 324705512/(1x842)

LCM = 324705512/842

LCM = 385636

Thus, we can understand that the LCM of 916,842,421 is 385636.

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

• LCM of 804, 300, 534
• LCM of 935, 480, 216
