Given numbers are 821,417,278

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

The LCM of 821,417,278 is 684714.

Find LCM of 821,417,278 with Prime Factorization

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

139 x 821 x 3 x 2 = 684714

Therefore, the lowest common multiple of 821,417,278 is 684714.

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.

821 x 417 x 278 = 95175246

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.

821 : 1, 821

417 : 1, 3, 139, 417

278 : 1, 2, 139, 278

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 821,417,278, is 1.

Now, the common factors can be found like this.

821:821

417:3x 139

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.

139 = 139

Therefore, the value for common factors is 139.

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 = 95175246/(1x139)

LCM = 95175246/139

LCM = 684714

Thus, we can understand that the LCM of 821,417,278 is 684714.

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

• LCM of 755, 802, 743
