Given numbers are 872,178,386,491

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

The LCM of 872,178,386,491 is 7354366904.

Find LCM of 872,178,386,491 with Prime Factorization

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

2 x 436 x 89 x 193 x 491 = 7354366904

Therefore, the lowest common multiple of 872,178,386,491 is 7354366904.

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.

872 x 178 x 386 x 491 = 29417467616

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.

872 : 1, 2, 4, 8, 109, 218, 436, 872

178 : 1, 2, 89, 178

386 : 1, 2, 193, 386

491 : 1, 491

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 872,178,386,491, is 1.

Now, the common factors can be found like this.

872:2x 2x 2x 109

178:2x 89

386:2x 193

491:491

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 = 29417467616/(1x4)

LCM = 29417467616/4

LCM = 7354366904

Thus, we can understand that the LCM of 872,178,386,491 is 7354366904.
