Given numbers are 401,840,646,479

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

The LCM of 401,840,646,479 is 52114874280.

Find LCM of 401,840,646,479 with Prime Factorization

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

2 x 401 x 420 x 323 x 479 = 52114874280

Therefore, the lowest common multiple of 401,840,646,479 is 52114874280.

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 840 x 646 x 479 = 104229748560

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

840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840

646 : 1, 2, 17, 19, 34, 38, 323, 646

479 : 1, 479

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 401,840,646,479, is 1.

Now, the common factors can be found like this.

401:401

840:2x 2x 2x 3x 5x 7

646:2x 17x 19

479:479

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

2 = 2

Therefore, the value for common factors is 2.

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 = 104229748560/(1x2)

LCM = 104229748560/2

LCM = 52114874280

Thus, we can understand that the LCM of 401,840,646,479 is 52114874280.
