Given numbers are 428,402,781,206

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

The LCM of 428,402,781,206 is 6920350404.

Find LCM of 428,402,781,206 with Prime Factorization

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

2 x 214 x 201 x 781 x 103 = 6920350404

Therefore, the lowest common multiple of 428,402,781,206 is 6920350404.

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 402 x 781 x 206 = 27681401616

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

402 : 1, 2, 3, 6, 67, 134, 201, 402

781 : 1, 11, 71, 781

206 : 1, 2, 103, 206

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 428,402,781,206, is 1.

Now, the common factors can be found like this.

428:2x 2x 107

402:2x 3x 67

781:11x 71

206:2x 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 = 27681401616/(1x4)

LCM = 27681401616/4

LCM = 6920350404

Thus, we can understand that the LCM of 428,402,781,206 is 6920350404.
