Given numbers are 155,438,467,478

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

The LCM of 155,438,467,478 is 7577406570.

Find LCM of 155,438,467,478 with Prime Factorization

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

2 x 155 x 219 x 467 x 239 = 7577406570

Therefore, the lowest common multiple of 155,438,467,478 is 7577406570.

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.

155 x 438 x 467 x 478 = 15154813140

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.

155 : 1, 5, 31, 155

438 : 1, 2, 3, 6, 73, 146, 219, 438

467 : 1, 467

478 : 1, 2, 239, 478

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 155,438,467,478, is 1.

Now, the common factors can be found like this.

155:5x 31

438:2x 3x 73

467:467

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 = 15154813140/(1x2)

LCM = 15154813140/2

LCM = 7577406570

Thus, we can understand that the LCM of 155,438,467,478 is 7577406570.
