Given numbers are 481,409,142,478

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

The LCM of 481,409,142,478 is 6676588802.

Find LCM of 481,409,142,478 with Prime Factorization

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

2 x 481 x 409 x 71 x 239 = 6676588802

Therefore, the lowest common multiple of 481,409,142,478 is 6676588802.

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.

481 x 409 x 142 x 478 = 13353177604

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.

481 : 1, 13, 37, 481

409 : 1, 409

142 : 1, 2, 71, 142

478 : 1, 2, 239, 478

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 481,409,142,478, is 1.

Now, the common factors can be found like this.

481:13x 37

409:409

142:2x 71

478:2x 239

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 = 13353177604/(1x2)

LCM = 13353177604/2

LCM = 6676588802

Thus, we can understand that the LCM of 481,409,142,478 is 6676588802.
