Given numbers are 428,415,781,108

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

The LCM of 428,415,781,108 is 3745472940.

Find LCM of 428,415,781,108 with Prime Factorization

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

2 x 2 x 107 x 415 x 781 x 27 = 3745472940

Therefore, the lowest common multiple of 428,415,781,108 is 3745472940.

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.

428 x 415 x 781 x 108 = 14981891760

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.

428 : 1, 2, 4, 107, 214, 428

415 : 1, 5, 83, 415

781 : 1, 11, 71, 781

108 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 108

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 428,415,781,108, is 1.

Now, the common factors can be found like this.

428:2x 2x 107

415:5x 83

781:11x 71

108:2x 2x 3x 3x 3

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 = 14981891760/(1x4)

LCM = 14981891760/4

LCM = 3745472940

Thus, we can understand that the LCM of 428,415,781,108 is 3745472940.
