Given numbers are 664,667,643,772

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

The LCM of 664,667,643,772 is 54961957912.

Find LCM of 664,667,643,772 with Prime Factorization

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

2 x 2 x 166 x 667 x 643 x 193 = 54961957912

Therefore, the lowest common multiple of 664,667,643,772 is 54961957912.

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.

664 x 667 x 643 x 772 = 219847831648

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.

664 : 1, 2, 4, 8, 83, 166, 332, 664

667 : 1, 23, 29, 667

643 : 1, 643

772 : 1, 2, 4, 193, 386, 772

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 664,667,643,772, is 1.

Now, the common factors can be found like this.

664:2x 2x 2x 83

667:23x 29

643:643

772:2x 2x 193

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 219847831648/(1x4)

LCM = 219847831648/4

LCM = 54961957912

Thus, we can understand that the LCM of 664,667,643,772 is 54961957912.
