Given numbers are 381,280,167,774

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

The LCM of 381,280,167,774 is 2298207240.

Find LCM of 381,280,167,774 with Prime Factorization

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

2 x 3 x 127 x 140 x 167 x 129 = 2298207240

Therefore, the lowest common multiple of 381,280,167,774 is 2298207240.

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.

381 x 280 x 167 x 774 = 13789243440

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.

381 : 1, 3, 127, 381

280 : 1, 2, 4, 5, 7, 8, 10, 14, 20, 28, 35, 40, 56, 70, 140, 280

167 : 1, 167

774 : 1, 2, 3, 6, 9, 18, 43, 86, 129, 258, 387, 774

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 381,280,167,774, is 1.

Now, the common factors can be found like this.

381:3x 127

280:2x 2x 2x 5x 7

167:167

774:2x 3x 3x 43

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

2x 3 = 6

Therefore, the value for common factors is 6.

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 = 13789243440/(1x6)

LCM = 13789243440/6

LCM = 2298207240

Thus, we can understand that the LCM of 381,280,167,774 is 2298207240.
