Given numbers are 947,389,891,451

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

The LCM of 947,389,891,451 is 13457399373.

Find LCM of 947,389,891,451 with Prime Factorization

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

11 x 947 x 389 x 81 x 41 = 13457399373

Therefore, the lowest common multiple of 947,389,891,451 is 13457399373.

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.

947 x 389 x 891 x 451 = 148031393103

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.

947 : 1, 947

389 : 1, 389

891 : 1, 3, 9, 11, 27, 33, 81, 99, 297, 891

451 : 1, 11, 41, 451

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 947,389,891,451, is 1.

Now, the common factors can be found like this.

947:947

389:389

891:3x 3x 3x 3x 11

451:11x 41

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

11 = 11

Therefore, the value for common factors is 11.

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 = 148031393103/(1x11)

LCM = 148031393103/11

LCM = 13457399373

Thus, we can understand that the LCM of 947,389,891,451 is 13457399373.
