Given numbers are 3,409,139,780

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

The LCM of 3,409,139,780 is 44343780.

Find LCM of 3,409,139,780 with Prime Factorization

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

3 x 1 x 409 x 139 x 260 = 44343780

Therefore, the lowest common multiple of 3,409,139,780 is 44343780.

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.

3 x 409 x 139 x 780 = 133031340

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.

3 : 1, 3

409 : 1, 409

139 : 1, 139

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 3,409,139,780, is 1.

Now, the common factors can be found like this.

3:3

409:409

139:139

780:2x 2x 3x 5x 13

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

3 = 3

Therefore, the value for common factors is 3.

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 = 133031340/(1x3)

LCM = 133031340/3

LCM = 44343780

Thus, we can understand that the LCM of 3,409,139,780 is 44343780.
