Given numbers are 391,139,402,304

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

The LCM of 391,139,402,304 is 3320941296.

Find LCM of 391,139,402,304 with Prime Factorization

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

2 x 391 x 139 x 201 x 152 = 3320941296

Therefore, the lowest common multiple of 391,139,402,304 is 3320941296.

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.

391 x 139 x 402 x 304 = 6641882592

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.

391 : 1, 17, 23, 391

139 : 1, 139

402 : 1, 2, 3, 6, 67, 134, 201, 402

304 : 1, 2, 4, 8, 16, 19, 38, 76, 152, 304

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 391,139,402,304, is 1.

Now, the common factors can be found like this.

391:17x 23

139:139

402:2x 3x 67

304:2x 2x 2x 2x 19

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 = 6641882592/(1x2)

LCM = 6641882592/2

LCM = 3320941296

Thus, we can understand that the LCM of 391,139,402,304 is 3320941296.
