Given numbers are 646,809,278

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

The LCM of 646,809,278 is 72643346.

Find LCM of 646,809,278 with Prime Factorization

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

2 x 323 x 809 x 139 = 72643346

Therefore, the lowest common multiple of 646,809,278 is 72643346.

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 809 x 278 = 145286692

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

809 : 1, 809

278 : 1, 2, 139, 278

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 646,809,278, is 1.

Now, the common factors can be found like this.

646:2x 17x 19

809:809

278:2x 139

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

2 = 2

Therefore, the value for common factors is 2.

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 = 145286692/(1x2)

LCM = 145286692/2

LCM = 72643346

Thus, we can understand that the LCM of 646,809,278 is 72643346.

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

• LCM of 755, 302, 997
• LCM of 327, 671, 990
