Given numbers are 681,624,821

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

The LCM of 681,624,821 is 116293008.

Find LCM of 681,624,821 with Prime Factorization

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

3 x 227 x 208 x 821 = 116293008

Therefore, the lowest common multiple of 681,624,821 is 116293008.

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.

681 x 624 x 821 = 348879024

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.

681 : 1, 3, 227, 681

624 : 1, 2, 3, 4, 6, 8, 12, 13, 16, 24, 26, 39, 48, 52, 78, 104, 156, 208, 312, 624

821 : 1, 821

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 681,624,821, is 1.

Now, the common factors can be found like this.

681:3x 227

624:2x 2x 2x 2x 3x 13

821:821

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

3 = 3

Therefore, the value for common factors is 3.

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 = 348879024/(1x3)

LCM = 348879024/3

LCM = 116293008

Thus, we can understand that the LCM of 681,624,821 is 116293008.

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

• LCM of 954, 298, 558
