Given numbers are 646,641,133

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

The LCM of 646,641,133 is 2898602.

Find LCM of 646,641,133 with Prime Factorization

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

19 x 34 x 641 x 7 = 2898602

Therefore, the lowest common multiple of 646,641,133 is 2898602.

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.

646 x 641 x 133 = 55073438

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.

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

641 : 1, 641

133 : 1, 7, 19, 133

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 646,641,133, is 1.

Now, the common factors can be found like this.

646:2x 17x 19

641:641

133:7x 19

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

19 = 19

Therefore, the value for common factors is 19.

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 = 55073438/(1x19)

LCM = 55073438/19

LCM = 2898602

Thus, we can understand that the LCM of 646,641,133 is 2898602.

Here are some samples of LCM of two or more Numbers calculations.

• LCM of 903, 900, 956
