Given numbers are 402,676,122,991,449

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

The LCM of 402,676,122,991,449 is 3688014194124.

Find LCM of 402,676,122,991,449 with Prime Factorization

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

2 x 201 x 338 x 61 x 991 x 449 = 3688014194124

Therefore, the lowest common multiple of 402,676,122,991,449 is 3688014194124.

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 676 x 122 x 991 x 449 = 14752056776496

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

676 : 1, 2, 4, 13, 26, 52, 169, 338, 676

122 : 1, 2, 61, 122

991 : 1, 991

449 : 1, 449

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 402,676,122,991,449, is 1.

Now, the common factors can be found like this.

402:2x 3x 67

676:2x 2x 13x 13

122:2x 61

991:991

449:449

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 14752056776496/(1x4)

LCM = 14752056776496/4

LCM = 3688014194124

Thus, we can understand that the LCM of 402,676,122,991,449 is 3688014194124.
