Given numbers are 685,218,905,275

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

The LCM of 685,218,905,275 is 1486580150.

Find LCM of 685,218,905,275 with Prime Factorization

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

5 x 137 x 218 x 181 x 55 = 1486580150

Therefore, the lowest common multiple of 685,218,905,275 is 1486580150.

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 218 x 905 x 275 = 37164503750

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

218 : 1, 2, 109, 218

905 : 1, 5, 181, 905

275 : 1, 5, 11, 25, 55, 275

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 685,218,905,275, is 1.

Now, the common factors can be found like this.

685:5x 137

218:2x 109

905:5x 181

275:5x 5x 11

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

5x 5 = 25

Therefore, the value for common factors is 25.

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 = 37164503750/(1x25)

LCM = 37164503750/25

LCM = 1486580150

Thus, we can understand that the LCM of 685,218,905,275 is 1486580150.
