Given numbers are 680,689,554

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

The LCM of 680,689,554 is 129780040.

Find LCM of 680,689,554 with Prime Factorization

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

2 x 340 x 689 x 277 = 129780040

Therefore, the lowest common multiple of 680,689,554 is 129780040.

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.

680 x 689 x 554 = 259560080

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.

680 : 1, 2, 4, 5, 8, 10, 17, 20, 34, 40, 68, 85, 136, 170, 340, 680

689 : 1, 13, 53, 689

554 : 1, 2, 277, 554

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 680,689,554, is 1.

Now, the common factors can be found like this.

680:2x 2x 2x 5x 17

689:13x 53

554:2x 277

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 = 259560080/(1x2)

LCM = 259560080/2

LCM = 129780040

Thus, we can understand that the LCM of 680,689,554 is 129780040.

Here are some samples of LCM of two or more Numbers calculations.

• LCM of 406, 710, 221
