Given numbers are 643,101,994,909

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

The LCM of 643,101,994,909 is 580980078.

Find LCM of 643,101,994,909 with Prime Factorization

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

101 x 643 x 1 x 994 x 9 = 580980078

Therefore, the lowest common multiple of 643,101,994,909 is 580980078.

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.

643 x 101 x 994 x 909 = 58678987878

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.

643 : 1, 643

101 : 1, 101

994 : 1, 2, 7, 14, 71, 142, 497, 994

909 : 1, 3, 9, 101, 303, 909

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 643,101,994,909, is 1.

Now, the common factors can be found like this.

643:643

101:101

994:2x 7x 71

909:3x 3x 101

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

101 = 101

Therefore, the value for common factors is 101.

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 = 58678987878/(1x101)

LCM = 58678987878/101

LCM = 580980078

Thus, we can understand that the LCM of 643,101,994,909 is 580980078.
