Given numbers are 409,447,604,689,755
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 409,447,604,689,755 is 380414441940.
Find LCM of 409,447,604,689,755 with Prime Factorization
151 | 409, 447, 604, 689, 755 |
409, 447, 4, 689, 5 |
Multiply the prime numbers at the bottom and the left side.
151 x 409 x 447 x 4 x 689 x 5 = 380414441940
Therefore, the lowest common multiple of 409,447,604,689,755 is 380414441940.
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.
409 x 447 x 604 x 689 x 755 = 57442580732940
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.
409 : 1, 409
447 : 1, 3, 149, 447
604 : 1, 2, 4, 151, 302, 604
689 : 1, 13, 53, 689
755 : 1, 5, 151, 755
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 409,447,604,689,755, is 1.
Now, the common factors can be found like this.
409:409
447:3x 149
604:2x 2x 151
689:13x 53
755:5x 151
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
151 = 151
Therefore, the value for common factors is 151.
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 = 57442580732940/(1x151)
LCM = 57442580732940/151
LCM = 380414441940
Thus, we can understand that the LCM of 409,447,604,689,755 is 380414441940.
