Given numbers are 689,654,212,235

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

The LCM of 689,654,212,235 is 211784820.

Find LCM of 689,654,212,235 with Prime Factorization

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

2 x 53 x 13 x 327 x 2 x 235 = 211784820

Therefore, the lowest common multiple of 689,654,212,235 is 211784820.

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.

689 x 654 x 212 x 235 = 22449190920

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.

689 : 1, 13, 53, 689

654 : 1, 2, 3, 6, 109, 218, 327, 654

212 : 1, 2, 4, 53, 106, 212

235 : 1, 5, 47, 235

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 689,654,212,235, is 1.

Now, the common factors can be found like this.

689:13x 53

654:2x 3x 109

212:2x 2x 53

235:5x 47

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

2x 53 = 106

Therefore, the value for common factors is 106.

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 = 22449190920/(1x106)

LCM = 22449190920/106

LCM = 211784820

Thus, we can understand that the LCM of 689,654,212,235 is 211784820.
