Given numbers are 218,993,545,689

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

The LCM of 218,993,545,689 is 745752930.

Find LCM of 218,993,545,689 with Prime Factorization

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

109 x 2 x 993 x 5 x 689 = 745752930

Therefore, the lowest common multiple of 218,993,545,689 is 745752930.

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.

218 x 993 x 545 x 689 = 81287069370

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.

218 : 1, 2, 109, 218

993 : 1, 3, 331, 993

545 : 1, 5, 109, 545

689 : 1, 13, 53, 689

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 218,993,545,689, is 1.

Now, the common factors can be found like this.

218:2x 109

993:3x 331

545:5x 109

689:13x 53

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

109 = 109

Therefore, the value for common factors is 109.

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 = 81287069370/(1x109)

LCM = 81287069370/109

LCM = 745752930

Thus, we can understand that the LCM of 218,993,545,689 is 745752930.
