Given numbers are 381,698,156,321

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

The LCM of 381,698,156,321 is 739839516.

Find LCM of 381,698,156,321 with Prime Factorization

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

2 x 3 x 127 x 349 x 26 x 107 = 739839516

Therefore, the lowest common multiple of 381,698,156,321 is 739839516.

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.

381 x 698 x 156 x 321 = 13317111288

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.

381 : 1, 3, 127, 381

698 : 1, 2, 349, 698

156 : 1, 2, 3, 4, 6, 12, 13, 26, 39, 52, 78, 156

321 : 1, 3, 107, 321

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 381,698,156,321, is 1.

Now, the common factors can be found like this.

381:3x 127

698:2x 349

156:2x 2x 3x 13

321:3x 107

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

2x 3x 3 = 18

Therefore, the value for common factors is 18.

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 = 13317111288/(1x18)

LCM = 13317111288/18

LCM = 739839516

Thus, we can understand that the LCM of 381,698,156,321 is 739839516.
