Given numbers are 489,947,215,947

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

The LCM of 489,947,215,947 is 99562845.

Find LCM of 489,947,215,947 with Prime Factorization

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

947 x 489 x 1 x 215 x 1 = 99562845

Therefore, the lowest common multiple of 489,947,215,947 is 99562845.

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.

489 x 947 x 215 x 947 = 94286014215

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.

489 : 1, 3, 163, 489

947 : 1, 947

215 : 1, 5, 43, 215

947 : 1, 947

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 489,947,215,947, is 1.

Now, the common factors can be found like this.

489:3x 163

947:947

215:5x 43

947:947

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

947 = 947

Therefore, the value for common factors is 947.

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 = 94286014215/(1x947)

LCM = 94286014215/947

LCM = 99562845

Thus, we can understand that the LCM of 489,947,215,947 is 99562845.
