Given numbers are 764,638,617,491

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

The LCM of 764,638,617,491 is 73833031052.

Find LCM of 764,638,617,491 with Prime Factorization

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

2 x 382 x 319 x 617 x 491 = 73833031052

Therefore, the lowest common multiple of 764,638,617,491 is 73833031052.

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.

764 x 638 x 617 x 491 = 147666062104

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.

764 : 1, 2, 4, 191, 382, 764

638 : 1, 2, 11, 22, 29, 58, 319, 638

617 : 1, 617

491 : 1, 491

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 764,638,617,491, is 1.

Now, the common factors can be found like this.

764:2x 2x 191

638:2x 11x 29

617:617

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.

2 = 2

Therefore, the value for common factors is 2.

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 = 147666062104/(1x2)

LCM = 147666062104/2

LCM = 73833031052

Thus, we can understand that the LCM of 764,638,617,491 is 73833031052.
