Given numbers are 400,171,129,718

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

The LCM of 400,171,129,718 is 1055890800.

Find LCM of 400,171,129,718 with Prime Factorization

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

2 x 3 x 200 x 57 x 43 x 359 = 1055890800

Therefore, the lowest common multiple of 400,171,129,718 is 1055890800.

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.

400 x 171 x 129 x 718 = 6335344800

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.

400 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 40, 50, 80, 100, 200, 400

171 : 1, 3, 9, 19, 57, 171

129 : 1, 3, 43, 129

718 : 1, 2, 359, 718

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 400,171,129,718, is 1.

Now, the common factors can be found like this.

400:2x 2x 2x 2x 5x 5

171:3x 3x 19

129:3x 43

718:2x 359

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

2x 3 = 6

Therefore, the value for common factors is 6.

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 = 6335344800/(1x6)

LCM = 6335344800/6

LCM = 1055890800

Thus, we can understand that the LCM of 400,171,129,718 is 1055890800.
