Given numbers are 617,429,689,491

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

The LCM of 617,429,689,491 is 6888105939.

Find LCM of 617,429,689,491 with Prime Factorization

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

13 x 617 x 33 x 53 x 491 = 6888105939

Therefore, the lowest common multiple of 617,429,689,491 is 6888105939.

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.

617 x 429 x 689 x 491 = 89545377207

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.

617 : 1, 617

429 : 1, 3, 11, 13, 33, 39, 143, 429

689 : 1, 13, 53, 689

491 : 1, 491

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 617,429,689,491, is 1.

Now, the common factors can be found like this.

617:617

429:3x 11x 13

689:13x 53

491:491

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 = 89545377207/(1x13)

LCM = 89545377207/13

LCM = 6888105939

Thus, we can understand that the LCM of 617,429,689,491 is 6888105939.
