Given numbers are 640,894,646,299,724

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

The LCM of 640,894,646,299,724 is 5000803416960.

Find LCM of 640,894,646,299,724 with Prime Factorization

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

2 x 2 x 160 x 447 x 323 x 299 x 181 = 5000803416960

Therefore, the lowest common multiple of 640,894,646,299,724 is 5000803416960.

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.

640 x 894 x 646 x 299 x 724 = 80012854671360

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.

640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640

894 : 1, 2, 3, 6, 149, 298, 447, 894

646 : 1, 2, 17, 19, 34, 38, 323, 646

299 : 1, 13, 23, 299

724 : 1, 2, 4, 181, 362, 724

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 640,894,646,299,724, is 1.

Now, the common factors can be found like this.

640:2x 2x 2x 2x 2x 2x 2x 5

894:2x 3x 149

646:2x 17x 19

299:13x 23

724:2x 2x 181

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 2x 2 = 16

Therefore, the value for common factors is 16.

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 = 80012854671360/(1x16)

LCM = 80012854671360/16

LCM = 5000803416960

Thus, we can understand that the LCM of 640,894,646,299,724 is 5000803416960.
