Given numbers are 685,432,778

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

The LCM of 685,432,778 is 115112880.

Find LCM of 685,432,778 with Prime Factorization

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

2 x 685 x 216 x 389 = 115112880

Therefore, the lowest common multiple of 685,432,778 is 115112880.

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.

685 x 432 x 778 = 230225760

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.

685 : 1, 5, 137, 685

432 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 36, 48, 54, 72, 108, 144, 216, 432

778 : 1, 2, 389, 778

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 685,432,778, is 1.

Now, the common factors can be found like this.

685:5x 137

432:2x 2x 2x 2x 3x 3x 3

778:2x 389

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 = 230225760/(1x2)

LCM = 230225760/2

LCM = 115112880

Thus, we can understand that the LCM of 685,432,778 is 115112880.
