Given numbers are 409,451,968,644,418
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 409,451,968,644,418 is 49654887128.
Find LCM of 409,451,968,644,418 with Prime Factorization
| 2 | 409, 451, 968, 644, 418 |
| 2 | 409, 451, 484, 322, 209 |
| 11 | 409, 451, 242, 161, 209 |
| 409, 41, 22, 161, 19 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 11 x 409 x 41 x 22 x 161 x 19 = 49654887128
Therefore, the lowest common multiple of 409,451,968,644,418 is 49654887128.
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 451 x 968 x 644 x 418 = 48065930739904
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
451 : 1, 11, 41, 451
968 : 1, 2, 4, 8, 11, 22, 44, 88, 121, 242, 484, 968
644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644
418 : 1, 2, 11, 19, 22, 38, 209, 418
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 409,451,968,644,418, is 1.
Now, the common factors can be found like this.
409:409
451:11x 41
968:2x 2x 2x 11x 11
644:2x 2x 7x 23
418:2x 11x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2x 11x 11 = 968
Therefore, the value for common factors is 968.
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 = 48065930739904/(1x968)
LCM = 48065930739904/968
LCM = 49654887128
Thus, we can understand that the LCM of 409,451,968,644,418 is 49654887128.
