Given numbers are 340,643,398,630

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

The LCM of 340,643,398,630 is 2740838940.

Find LCM of 340,643,398,630 with Prime Factorization

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

2 x 5 x 34 x 643 x 199 x 63 = 2740838940

Therefore, the lowest common multiple of 340,643,398,630 is 2740838940.

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.

340 x 643 x 398 x 630 = 54816778800

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.

340 : 1, 2, 4, 5, 10, 17, 20, 34, 68, 85, 170, 340

643 : 1, 643

398 : 1, 2, 199, 398

630 : 1, 2, 3, 5, 6, 7, 9, 10, 14, 15, 18, 21, 30, 35, 42, 45, 63, 70, 90, 105, 126, 210, 315, 630

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 340,643,398,630, is 1.

Now, the common factors can be found like this.

340:2x 2x 5x 17

643:643

398:2x 199

630:2x 3x 3x 5x 7

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 5 = 20

Therefore, the value for common factors is 20.

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 = 54816778800/(1x20)

LCM = 54816778800/20

LCM = 2740838940

Thus, we can understand that the LCM of 340,643,398,630 is 2740838940.
