Given numbers are 287,578,422

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

The LCM of 287,578,422 is 35001946.

Find LCM of 287,578,422 with Prime Factorization

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

2 x 287 x 289 x 211 = 35001946

Therefore, the lowest common multiple of 287,578,422 is 35001946.

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.

287 x 578 x 422 = 70003892

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.

287 : 1, 7, 41, 287

578 : 1, 2, 17, 34, 289, 578

422 : 1, 2, 211, 422

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 287,578,422, is 1.

Now, the common factors can be found like this.

287:7x 41

578:2x 17x 17

422:2x 211

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

2 = 2

Therefore, the value for common factors is 2.

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 = 70003892/(1x2)

LCM = 70003892/2

LCM = 35001946

Thus, we can understand that the LCM of 287,578,422 is 35001946.

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

• LCM of 264, 968, 198
• LCM of 568, 351, 899
