Given numbers are 821,116,435

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

The LCM of 821,116,435 is 1428540.

Find LCM of 821,116,435 with Prime Factorization

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

29 x 821 x 4 x 15 = 1428540

Therefore, the lowest common multiple of 821,116,435 is 1428540.

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.

821 x 116 x 435 = 41427660

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.

821 : 1, 821

116 : 1, 2, 4, 29, 58, 116

435 : 1, 3, 5, 15, 29, 87, 145, 435

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 821,116,435, is 1.

Now, the common factors can be found like this.

821:821

116:2x 2x 29

435:3x 5x 29

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

29 = 29

Therefore, the value for common factors is 29.

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 = 41427660/(1x29)

LCM = 41427660/29

LCM = 1428540

Thus, we can understand that the LCM of 821,116,435 is 1428540.

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

• LCM of 560, 510, 648
• LCM of 478, 918, 463
