Given numbers are 401,642,718,424

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

The LCM of 401,642,718,424 is 19593395736.

Find LCM of 401,642,718,424 with Prime Factorization

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

2 x 401 x 321 x 359 x 212 = 19593395736

Therefore, the lowest common multiple of 401,642,718,424 is 19593395736.

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 642 x 718 x 424 = 78373582944

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

642 : 1, 2, 3, 6, 107, 214, 321, 642

718 : 1, 2, 359, 718

424 : 1, 2, 4, 8, 53, 106, 212, 424

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 401,642,718,424, is 1.

Now, the common factors can be found like this.

401:401

642:2x 3x 107

718:2x 359

424:2x 2x 2x 53

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 = 78373582944/(1x4)

LCM = 78373582944/4

LCM = 19593395736

Thus, we can understand that the LCM of 401,642,718,424 is 19593395736.
