Given numbers are 394,790,780,540,372

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

The LCM of 394,790,780,540,372 is 3386820060.

Find LCM of 394,790,780,540,372 with Prime Factorization

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

2 x 2 x 3 x 5 x 197 x 79 x 13 x 9 x 31 = 3386820060

Therefore, the lowest common multiple of 394,790,780,540,372 is 3386820060.

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.

394 x 790 x 780 x 540 x 372 = 48770208864000

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.

394 : 1, 2, 197, 394

790 : 1, 2, 5, 10, 79, 158, 395, 790

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

540 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 27, 30, 36, 45, 54, 60, 90, 108, 135, 180, 270, 540

372 : 1, 2, 3, 4, 6, 12, 31, 62, 93, 124, 186, 372

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 394,790,780,540,372, is 2.

Now, the common factors can be found like this.

394:2x 197

790:2x 5x 79

780:2x 2x 3x 5x 13

540:2x 2x 3x 3x 3x 5

372:2x 2x 3x 31

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 2x 3x 3x 5x 5 = 7200

Therefore, the value for common factors is 7200.

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 = 48770208864000/(2x7200)

LCM = 48770208864000/14400

LCM = 3386820060

Thus, we can understand that the LCM of 394,790,780,540,372 is 3386820060.
