Given numbers are 307,858,720,685

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

The LCM of 307,858,720,685 is 4330394640.

Find LCM of 307,858,720,685 with Prime Factorization

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

2 x 3 x 5 x 307 x 143 x 24 x 137 = 4330394640

Therefore, the lowest common multiple of 307,858,720,685 is 4330394640.

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.

307 x 858 x 720 x 685 = 129911839200

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.

307 : 1, 307

858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858

720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720

685 : 1, 5, 137, 685

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 307,858,720,685, is 1.

Now, the common factors can be found like this.

307:307

858:2x 3x 11x 13

720:2x 2x 2x 2x 3x 3x 5

685:5x 137

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 5 = 30

Therefore, the value for common factors is 30.

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 = 129911839200/(1x30)

LCM = 129911839200/30

LCM = 4330394640

Thus, we can understand that the LCM of 307,858,720,685 is 4330394640.
