Given numbers are 905,641,664,498

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

The LCM of 905,641,664,498 is 1155569160.

Find LCM of 905,641,664,498 with Prime Factorization

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

2 x 83 x 905 x 641 x 4 x 3 = 1155569160

Therefore, the lowest common multiple of 905,641,664,498 is 1155569160.

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 641 x 664 x 498 = 191824480560

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

641 : 1, 641

664 : 1, 2, 4, 8, 83, 166, 332, 664

498 : 1, 2, 3, 6, 83, 166, 249, 498

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 905,641,664,498, is 1.

Now, the common factors can be found like this.

905:5x 181

641:641

664:2x 2x 2x 83

498:2x 3x 83

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

2x 83 = 166

Therefore, the value for common factors is 166.

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 = 191824480560/(1x166)

LCM = 191824480560/166

LCM = 1155569160

Thus, we can understand that the LCM of 905,641,664,498 is 1155569160.
