Given numbers are 645,889,334,730

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

The LCM of 645,889,334,730 is 13980760710.

Find LCM of 645,889,334,730 with Prime Factorization

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

2 x 5 x 129 x 889 x 167 x 73 = 13980760710

Therefore, the lowest common multiple of 645,889,334,730 is 13980760710.

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.

645 x 889 x 334 x 730 = 139807607100

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.

645 : 1, 3, 5, 15, 43, 129, 215, 645

889 : 1, 7, 127, 889

334 : 1, 2, 167, 334

730 : 1, 2, 5, 10, 73, 146, 365, 730

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 645,889,334,730, is 1.

Now, the common factors can be found like this.

645:3x 5x 43

889:7x 127

334:2x 167

730:2x 5x 73

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 = 139807607100/(1x10)

LCM = 139807607100/10

LCM = 13980760710

Thus, we can understand that the LCM of 645,889,334,730 is 13980760710.
