Given numbers are 689,463,689,621

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

The LCM of 689,463,689,621 is 198103347.

Find LCM of 689,463,689,621 with Prime Factorization

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

13 x 53 x 1 x 463 x 1 x 621 = 198103347

Therefore, the lowest common multiple of 689,463,689,621 is 198103347.

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 463 x 689 x 621 = 136493206083

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

463 : 1, 463

689 : 1, 13, 53, 689

621 : 1, 3, 9, 23, 27, 69, 207, 621

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 689,463,689,621, is 1.

Now, the common factors can be found like this.

689:13x 53

463:463

689:13x 53

621:3x 3x 3x 23

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

13x 53 = 689

Therefore, the value for common factors is 689.

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 = 136493206083/(1x689)

LCM = 136493206083/689

LCM = 198103347

Thus, we can understand that the LCM of 689,463,689,621 is 198103347.
