Given numbers are 343,190,398,521

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

The LCM of 343,190,398,521 is 6756760430.

Find LCM of 343,190,398,521 with Prime Factorization

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

2 x 343 x 95 x 199 x 521 = 6756760430

Therefore, the lowest common multiple of 343,190,398,521 is 6756760430.

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 190 x 398 x 521 = 13513520860

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

190 : 1, 2, 5, 10, 19, 38, 95, 190

398 : 1, 2, 199, 398

521 : 1, 521

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 343,190,398,521, is 1.

Now, the common factors can be found like this.

343:7x 7x 7

190:2x 5x 19

398:2x 199

521:521

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

2 = 2

Therefore, the value for common factors is 2.

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 = 13513520860/(1x2)

LCM = 13513520860/2

LCM = 6756760430

Thus, we can understand that the LCM of 343,190,398,521 is 6756760430.
