Given numbers are 478,646,487

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

The LCM of 478,646,487 is 75189878.

Find LCM of 478,646,487 with Prime Factorization

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

2 x 239 x 323 x 487 = 75189878

Therefore, the lowest common multiple of 478,646,487 is 75189878.

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.

478 x 646 x 487 = 150379756

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.

478 : 1, 2, 239, 478

646 : 1, 2, 17, 19, 34, 38, 323, 646

487 : 1, 487

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 478,646,487, is 1.

Now, the common factors can be found like this.

478:2x 239

646:2x 17x 19

487:487

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 = 150379756/(1x2)

LCM = 150379756/2

LCM = 75189878

Thus, we can understand that the LCM of 478,646,487 is 75189878.

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

• LCM of 171, 484, 998
• LCM of 915, 210, 976
• LCM of 130, 502, 941
