Given numbers are 617,643,506,764

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

The LCM of 617,643,506,764 is 76684928452.

Find LCM of 617,643,506,764 with Prime Factorization

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

2 x 617 x 643 x 253 x 382 = 76684928452

Therefore, the lowest common multiple of 617,643,506,764 is 76684928452.

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 643 x 506 x 764 = 153369856904

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

643 : 1, 643

506 : 1, 2, 11, 22, 23, 46, 253, 506

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 617,643,506,764, is 1.

Now, the common factors can be found like this.

617:617

643:643

506:2x 11x 23

764:2x 2x 191

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 = 153369856904/(1x2)

LCM = 153369856904/2

LCM = 76684928452

Thus, we can understand that the LCM of 617,643,506,764 is 76684928452.
