Given numbers are 401,712,802,409

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

The LCM of 401,712,802,409 is 116774408.

Find LCM of 401,712,802,409 with Prime Factorization

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

2 x 401 x 1 x 356 x 1 x 409 = 116774408

Therefore, the lowest common multiple of 401,712,802,409 is 116774408.

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.

401 x 712 x 802 x 409 = 93653075216

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.

401 : 1, 401

712 : 1, 2, 4, 8, 89, 178, 356, 712

802 : 1, 2, 401, 802

409 : 1, 409

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 401,712,802,409, is 1.

Now, the common factors can be found like this.

401:401

712:2x 2x 2x 89

802:2x 401

409:409

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

2x 401 = 802

Therefore, the value for common factors is 802.

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 = 93653075216/(1x802)

LCM = 93653075216/802

LCM = 116774408

Thus, we can understand that the LCM of 401,712,802,409 is 116774408.
