Given numbers are 217,407,539,616
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 217,407,539,616 is 4945864.
Find LCM of 217,407,539,616 with Prime Factorization
| 7 | 217, 407, 539, 616 |
| 11 | 31, 407, 77, 88 |
| 31, 37, 7, 8 |
Multiply the prime numbers at the bottom and the left side.
7 x 11 x 31 x 37 x 7 x 8 = 4945864
Therefore, the lowest common multiple of 217,407,539,616 is 4945864.
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.
217 x 407 x 539 x 616 = 29324027656
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.
217 : 1, 7, 31, 217
407 : 1, 11, 37, 407
539 : 1, 7, 11, 49, 77, 539
616 : 1, 2, 4, 7, 8, 11, 14, 22, 28, 44, 56, 77, 88, 154, 308, 616
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 217,407,539,616, is 1.
Now, the common factors can be found like this.
217:7x 31
407:11x 37
539:7x 7x 11
616:2x 2x 2x 7x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
7x 7x 11x 11 = 5929
Therefore, the value for common factors is 5929.
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 = 29324027656/(1x5929)
LCM = 29324027656/5929
LCM = 4945864
Thus, we can understand that the LCM of 217,407,539,616 is 4945864.
