Given numbers are 905,880,616,418

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

The LCM of 905,880,616,418 is 21184240.

Find LCM of 905,880,616,418 with Prime Factorization

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

2 x 2 x 2 x 5 x 11 x 181 x 2 x 7 x 19 = 21184240

Therefore, the lowest common multiple of 905,880,616,418 is 21184240.

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.

905 x 880 x 616 x 418 = 205063443200

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.

905 : 1, 5, 181, 905

880 : 1, 2, 4, 5, 8, 10, 11, 16, 20, 22, 40, 44, 55, 80, 88, 110, 176, 220, 440, 880

616 : 1, 2, 4, 7, 8, 11, 14, 22, 28, 44, 56, 77, 88, 154, 308, 616

418 : 1, 2, 11, 19, 22, 38, 209, 418

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 905,880,616,418, is 1.

Now, the common factors can be found like this.

905:5x 181

880:2x 2x 2x 2x 5x 11

616:2x 2x 2x 7x 11

418:2x 11x 19

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 5x 11x 11 = 9680

Therefore, the value for common factors is 9680.

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 = 205063443200/(1x9680)

LCM = 205063443200/9680

LCM = 21184240

Thus, we can understand that the LCM of 905,880,616,418 is 21184240.
