Given numbers are 662,605,285,428

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

The LCM of 662,605,285,428 is 4885420980.

Find LCM of 662,605,285,428 with Prime Factorization

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

2 x 5 x 331 x 121 x 57 x 214 = 4885420980

Therefore, the lowest common multiple of 662,605,285,428 is 4885420980.

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.

662 x 605 x 285 x 428 = 48854209800

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.

662 : 1, 2, 331, 662

605 : 1, 5, 11, 55, 121, 605

285 : 1, 3, 5, 15, 19, 57, 95, 285

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 662,605,285,428, is 1.

Now, the common factors can be found like this.

662:2x 331

605:5x 11x 11

285:3x 5x 19

428:2x 2x 107

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 = 48854209800/(1x10)

LCM = 48854209800/10

LCM = 4885420980

Thus, we can understand that the LCM of 662,605,285,428 is 4885420980.
