Given numbers are 706,130,690,780

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

The LCM of 706,130,690,780 is 6332820.

Find LCM of 706,130,690,780 with Prime Factorization

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

2 x 3 x 5 x 13 x 353 x 1 x 23 x 2 = 6332820

Therefore, the lowest common multiple of 706,130,690,780 is 6332820.

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.

706 x 130 x 690 x 780 = 49395996000

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.

706 : 1, 2, 353, 706

130 : 1, 2, 5, 10, 13, 26, 65, 130

690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690

780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 706,130,690,780, is 2.

Now, the common factors can be found like this.

706:2x 353

130:2x 5x 13

690:2x 3x 5x 23

780:2x 2x 3x 5x 13

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 3x 5x 5x 13 = 3900

Therefore, the value for common factors is 3900.

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 = 49395996000/(2x3900)

LCM = 49395996000/7800

LCM = 6332820

Thus, we can understand that the LCM of 706,130,690,780 is 6332820.
