Given numbers are 402,104,821,813

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

The LCM of 402,104,821,813 is 4650951864.

Find LCM of 402,104,821,813 with Prime Factorization

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

2 x 3 x 67 x 52 x 821 x 271 = 4650951864

Therefore, the lowest common multiple of 402,104,821,813 is 4650951864.

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.

402 x 104 x 821 x 813 = 27905711184

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.

402 : 1, 2, 3, 6, 67, 134, 201, 402

104 : 1, 2, 4, 8, 13, 26, 52, 104

821 : 1, 821

813 : 1, 3, 271, 813

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 402,104,821,813, is 1.

Now, the common factors can be found like this.

402:2x 3x 67

104:2x 2x 2x 13

821:821

813:3x 271

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

2x 3 = 6

Therefore, the value for common factors is 6.

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 = 27905711184/(1x6)

LCM = 27905711184/6

LCM = 4650951864

Thus, we can understand that the LCM of 402,104,821,813 is 4650951864.
