Given numbers are 402,856,717,390

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

The LCM of 402,856,717,390 is 2672889960.

Find LCM of 402,856,717,390 with Prime Factorization

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

2 x 3 x 67 x 428 x 239 x 65 = 2672889960

Therefore, the lowest common multiple of 402,856,717,390 is 2672889960.

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.

402 x 856 x 717 x 390 = 96224038560

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.

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

856 : 1, 2, 4, 8, 107, 214, 428, 856

717 : 1, 3, 239, 717

390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 402,856,717,390, is 1.

Now, the common factors can be found like this.

402:2x 3x 67

856:2x 2x 2x 107

717:3x 239

390:2x 3x 5x 13

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

2x 2x 3x 3 = 36

Therefore, the value for common factors is 36.

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 = 96224038560/(1x36)

LCM = 96224038560/36

LCM = 2672889960

Thus, we can understand that the LCM of 402,856,717,390 is 2672889960.
