Given numbers are 672,596,644,643

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

The LCM of 672,596,644,643 is 1480792992.

Find LCM of 672,596,644,643 with Prime Factorization

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

2 x 2 x 7 x 24 x 149 x 23 x 643 = 1480792992

Therefore, the lowest common multiple of 672,596,644,643 is 1480792992.

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.

672 x 596 x 644 x 643 = 165848815104

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.

672 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 16, 21, 24, 28, 32, 42, 48, 56, 84, 96, 112, 168, 224, 336, 672

596 : 1, 2, 4, 149, 298, 596

644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644

643 : 1, 643

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 672,596,644,643, is 1.

Now, the common factors can be found like this.

672:2x 2x 2x 2x 2x 3x 7

596:2x 2x 149

644:2x 2x 7x 23

643:643

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

2x 2x 2x 2x 7 = 112

Therefore, the value for common factors is 112.

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 = 165848815104/(1x112)

LCM = 165848815104/112

LCM = 1480792992

Thus, we can understand that the LCM of 672,596,644,643 is 1480792992.
