Given numbers are 818,720,163,896

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

The LCM of 818,720,163,896 is 2688013440.

Find LCM of 818,720,163,896 with Prime Factorization

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

2 x 2 x 2 x 2 x 409 x 45 x 163 x 56 = 2688013440

Therefore, the lowest common multiple of 818,720,163,896 is 2688013440.

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.

818 x 720 x 163 x 896 = 86016430080

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.

818 : 1, 2, 409, 818

720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720

163 : 1, 163

896 : 1, 2, 4, 7, 8, 14, 16, 28, 32, 56, 64, 112, 128, 224, 448, 896

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 818,720,163,896, is 1.

Now, the common factors can be found like this.

818:2x 409

720:2x 2x 2x 2x 3x 3x 5

163:163

896:2x 2x 2x 2x 2x 2x 2x 7

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

2x 2x 2x 2x 2 = 32

Therefore, the value for common factors is 32.

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 = 86016430080/(1x32)

LCM = 86016430080/32

LCM = 2688013440

Thus, we can understand that the LCM of 818,720,163,896 is 2688013440.
