Given numbers are 489,289,785,628

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

The LCM of 489,289,785,628 is 443747940.

Find LCM of 489,289,785,628 with Prime Factorization

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

157 x 489 x 289 x 5 x 4 = 443747940

Therefore, the lowest common multiple of 489,289,785,628 is 443747940.

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.

489 x 289 x 785 x 628 = 69668426580

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.

489 : 1, 3, 163, 489

289 : 1, 17, 289

785 : 1, 5, 157, 785

628 : 1, 2, 4, 157, 314, 628

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 489,289,785,628, is 1.

Now, the common factors can be found like this.

489:3x 163

289:17x 17

785:5x 157

628:2x 2x 157

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

157 = 157

Therefore, the value for common factors is 157.

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 = 69668426580/(1x157)

LCM = 69668426580/157

LCM = 443747940

Thus, we can understand that the LCM of 489,289,785,628 is 443747940.
