Given numbers are 700,660,406,430

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

The LCM of 700,660,406,430 is 28805700.

Find LCM of 700,660,406,430 with Prime Factorization

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

2 x 2 x 5 x 7 x 5 x 33 x 29 x 43 = 28805700

Therefore, the lowest common multiple of 700,660,406,430 is 28805700.

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.

700 x 660 x 406 x 430 = 80655960000

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.

700 : 1, 2, 4, 5, 7, 10, 14, 20, 25, 28, 35, 50, 70, 100, 140, 175, 350, 700

660 : 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660

406 : 1, 2, 7, 14, 29, 58, 203, 406

430 : 1, 2, 5, 10, 43, 86, 215, 430

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 700,660,406,430, is 2.

Now, the common factors can be found like this.

700:2x 2x 5x 5x 7

660:2x 2x 3x 5x 11

406:2x 7x 29

430:2x 5x 43

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 5x 5x 7 = 1400

Therefore, the value for common factors is 1400.

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 = 80655960000/(2x1400)

LCM = 80655960000/2800

LCM = 28805700

Thus, we can understand that the LCM of 700,660,406,430 is 28805700.
