Given numbers are 782,979,346,820

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

The LCM of 782,979,346,820 is 54302447540.

Find LCM of 782,979,346,820 with Prime Factorization

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

2 x 391 x 979 x 173 x 410 = 54302447540

Therefore, the lowest common multiple of 782,979,346,820 is 54302447540.

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.

782 x 979 x 346 x 820 = 217209790160

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.

782 : 1, 2, 17, 23, 34, 46, 391, 782

979 : 1, 11, 89, 979

346 : 1, 2, 173, 346

820 : 1, 2, 4, 5, 10, 20, 41, 82, 164, 205, 410, 820

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 782,979,346,820, is 1.

Now, the common factors can be found like this.

782:2x 17x 23

979:11x 89

346:2x 173

820:2x 2x 5x 41

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 = 217209790160/(1x4)

LCM = 217209790160/4

LCM = 54302447540

Thus, we can understand that the LCM of 782,979,346,820 is 54302447540.
