Given numbers are 401,328,831,686

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

The LCM of 401,328,831,686 is 37489820424.

Find LCM of 401,328,831,686 with Prime Factorization

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

2 x 401 x 164 x 831 x 343 = 37489820424

Therefore, the lowest common multiple of 401,328,831,686 is 37489820424.

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 328 x 831 x 686 = 74979640848

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

328 : 1, 2, 4, 8, 41, 82, 164, 328

831 : 1, 3, 277, 831

686 : 1, 2, 7, 14, 49, 98, 343, 686

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 401,328,831,686, is 1.

Now, the common factors can be found like this.

401:401

328:2x 2x 2x 41

831:3x 277

686:2x 7x 7x 7

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 = 74979640848/(1x2)

LCM = 74979640848/2

LCM = 37489820424

Thus, we can understand that the LCM of 401,328,831,686 is 37489820424.
