Given numbers are 687,551,970,406

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

The LCM of 687,551,970,406 is 2570266230.

Find LCM of 687,551,970,406 with Prime Factorization

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

2 x 29 x 687 x 19 x 485 x 7 = 2570266230

Therefore, the lowest common multiple of 687,551,970,406 is 2570266230.

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.

687 x 551 x 970 x 406 = 149075441340

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.

687 : 1, 3, 229, 687

551 : 1, 19, 29, 551

970 : 1, 2, 5, 10, 97, 194, 485, 970

406 : 1, 2, 7, 14, 29, 58, 203, 406

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 687,551,970,406, is 1.

Now, the common factors can be found like this.

687:3x 229

551:19x 29

970:2x 5x 97

406:2x 7x 29

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

2x 29 = 58

Therefore, the value for common factors is 58.

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 = 149075441340/(1x58)

LCM = 149075441340/58

LCM = 2570266230

Thus, we can understand that the LCM of 687,551,970,406 is 2570266230.
