Given numbers are 905,559,689,671

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

The LCM of 905,559,689,671 is 17991143885.

Find LCM of 905,559,689,671 with Prime Factorization

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

13 x 905 x 43 x 53 x 671 = 17991143885

Therefore, the lowest common multiple of 905,559,689,671 is 17991143885.

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 559 x 689 x 671 = 233884870505

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

559 : 1, 13, 43, 559

689 : 1, 13, 53, 689

671 : 1, 11, 61, 671

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 905,559,689,671, is 1.

Now, the common factors can be found like this.

905:5x 181

559:13x 43

689:13x 53

671:11x 61

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

13 = 13

Therefore, the value for common factors is 13.

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 = 233884870505/(1x13)

LCM = 233884870505/13

LCM = 17991143885

Thus, we can understand that the LCM of 905,559,689,671 is 17991143885.
