Given numbers are 386,148,781,618

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

The LCM of 386,148,781,618 is 6893321556.

Find LCM of 386,148,781,618 with Prime Factorization

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

2 x 193 x 74 x 781 x 309 = 6893321556

Therefore, the lowest common multiple of 386,148,781,618 is 6893321556.

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.

386 x 148 x 781 x 618 = 27573286224

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.

386 : 1, 2, 193, 386

148 : 1, 2, 4, 37, 74, 148

781 : 1, 11, 71, 781

618 : 1, 2, 3, 6, 103, 206, 309, 618

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 386,148,781,618, is 1.

Now, the common factors can be found like this.

386:2x 193

148:2x 2x 37

781:11x 71

618:2x 3x 103

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 27573286224/(1x4)

LCM = 27573286224/4

LCM = 6893321556

Thus, we can understand that the LCM of 386,148,781,618 is 6893321556.
