Given numbers are 687,194,986,357

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

The LCM of 687,194,986,357 is 459942378.

Find LCM of 687,194,986,357 with Prime Factorization

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

2 x 3 x 17 x 229 x 97 x 29 x 7 = 459942378

Therefore, the lowest common multiple of 687,194,986,357 is 459942378.

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 194 x 986 x 357 = 46914122556

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

194 : 1, 2, 97, 194

986 : 1, 2, 17, 29, 34, 58, 493, 986

357 : 1, 3, 7, 17, 21, 51, 119, 357

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 687,194,986,357, is 1.

Now, the common factors can be found like this.

687:3x 229

194:2x 97

986:2x 17x 29

357:3x 7x 17

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

2x 3x 17 = 102

Therefore, the value for common factors is 102.

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 = 46914122556/(1x102)

LCM = 46914122556/102

LCM = 459942378

Thus, we can understand that the LCM of 687,194,986,357 is 459942378.
