Given numbers are 380,445,149,786

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

The LCM of 380,445,149,786 is 1980397740.

Find LCM of 380,445,149,786 with Prime Factorization

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

2 x 5 x 38 x 89 x 149 x 393 = 1980397740

Therefore, the lowest common multiple of 380,445,149,786 is 1980397740.

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.

380 x 445 x 149 x 786 = 19803977400

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.

380 : 1, 2, 4, 5, 10, 19, 20, 38, 76, 95, 190, 380

445 : 1, 5, 89, 445

149 : 1, 149

786 : 1, 2, 3, 6, 131, 262, 393, 786

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 380,445,149,786, is 1.

Now, the common factors can be found like this.

380:2x 2x 5x 19

445:5x 89

149:149

786:2x 3x 131

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

2x 5 = 10

Therefore, the value for common factors is 10.

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 = 19803977400/(1x10)

LCM = 19803977400/10

LCM = 1980397740

Thus, we can understand that the LCM of 380,445,149,786 is 1980397740.
