Given numbers are 912,207,640,669

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

The LCM of 912,207,640,669 is 561317760.

Find LCM of 912,207,640,669 with Prime Factorization

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

2 x 2 x 2 x 2 x 3 x 19 x 69 x 40 x 223 = 561317760

Therefore, the lowest common multiple of 912,207,640,669 is 561317760.

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.

912 x 207 x 640 x 669 = 80829757440

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.

912 : 1, 2, 3, 4, 6, 8, 12, 16, 19, 24, 38, 48, 57, 76, 114, 152, 228, 304, 456, 912

207 : 1, 3, 9, 23, 69, 207

640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640

669 : 1, 3, 223, 669

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 912,207,640,669, is 1.

Now, the common factors can be found like this.

912:2x 2x 2x 2x 3x 19

207:3x 3x 23

640:2x 2x 2x 2x 2x 2x 2x 5

669:3x 223

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 3x 3 = 144

Therefore, the value for common factors is 144.

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 = 80829757440/(1x144)

LCM = 80829757440/144

LCM = 561317760

Thus, we can understand that the LCM of 912,207,640,669 is 561317760.
