Given numbers are 670,408,102,782,811

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

The LCM of 670,408,102,782,811 is 2549492040.

Find LCM of 670,408,102,782,811 with Prime Factorization

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

2 x 3 x 17 x 335 x 4 x 1 x 23 x 811 = 2549492040

Therefore, the lowest common multiple of 670,408,102,782,811 is 2549492040.

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.

670 x 408 x 102 x 782 x 811 = 17683276789440

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.

670 : 1, 2, 5, 10, 67, 134, 335, 670

408 : 1, 2, 3, 4, 6, 8, 12, 17, 24, 34, 51, 68, 102, 136, 204, 408

102 : 1, 2, 3, 6, 17, 34, 51, 102

782 : 1, 2, 17, 23, 34, 46, 391, 782

811 : 1, 811

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 670,408,102,782,811, is 1.

Now, the common factors can be found like this.

670:2x 5x 67

408:2x 2x 2x 3x 17

102:2x 3x 17

782:2x 17x 23

811:811

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 3x 17x 17 = 6936

Therefore, the value for common factors is 6936.

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 = 17683276789440/(1x6936)

LCM = 17683276789440/6936

LCM = 2549492040

Thus, we can understand that the LCM of 670,408,102,782,811 is 2549492040.
