Given numbers are 343,798,982,168,780

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

The LCM of 343,798,982,168,780 is 4991761320.

Find LCM of 343,798,982,168,780 with Prime Factorization

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

2 x 2 x 3 x 7 x 49 x 19 x 491 x 2 x 65 = 4991761320

Therefore, the lowest common multiple of 343,798,982,168,780 is 4991761320.

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.

343 x 798 x 982 x 168 x 780 = 35221867873920

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.

343 : 1, 7, 49, 343

798 : 1, 2, 3, 6, 7, 14, 19, 21, 38, 42, 57, 114, 133, 266, 399, 798

982 : 1, 2, 491, 982

168 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 21, 24, 28, 42, 56, 84, 168

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 343,798,982,168,780, is 1.

Now, the common factors can be found like this.

343:7x 7x 7

798:2x 3x 7x 19

982:2x 491

168:2x 2x 2x 3x 7

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 2x 2x 3x 3x 7x 7 = 7056

Therefore, the value for common factors is 7056.

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 = 35221867873920/(1x7056)

LCM = 35221867873920/7056

LCM = 4991761320

Thus, we can understand that the LCM of 343,798,982,168,780 is 4991761320.
