Given numbers are 401,778,778,135

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

The LCM of 401,778,778,135 is 42117030.

Find LCM of 401,778,778,135 with Prime Factorization

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

2 x 389 x 401 x 1 x 1 x 135 = 42117030

Therefore, the lowest common multiple of 401,778,778,135 is 42117030.

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 778 x 778 x 135 = 32767049340

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

778 : 1, 2, 389, 778

778 : 1, 2, 389, 778

135 : 1, 3, 5, 9, 15, 27, 45, 135

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 401,778,778,135, is 1.

Now, the common factors can be found like this.

401:401

778:2x 389

778:2x 389

135:3x 3x 3x 5

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

2x 389 = 778

Therefore, the value for common factors is 778.

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 = 32767049340/(1x778)

LCM = 32767049340/778

LCM = 42117030

Thus, we can understand that the LCM of 401,778,778,135 is 42117030.
