Given numbers are 727,643,643,454

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

The LCM of 727,643,643,454 is 212227294.

Find LCM of 727,643,643,454 with Prime Factorization

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

643 x 727 x 1 x 1 x 454 = 212227294

Therefore, the lowest common multiple of 727,643,643,454 is 212227294.

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.

727 x 643 x 643 x 454 = 136462150042

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.

727 : 1, 727

643 : 1, 643

643 : 1, 643

454 : 1, 2, 227, 454

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 727,643,643,454, is 1.

Now, the common factors can be found like this.

727:727

643:643

643:643

454:2x 227

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

643 = 643

Therefore, the value for common factors is 643.

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 = 136462150042/(1x643)

LCM = 136462150042/643

LCM = 212227294

Thus, we can understand that the LCM of 727,643,643,454 is 212227294.
