Given numbers are 218,407,836,968
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 218,407,836,968 is 74174936.
Find LCM of 218,407,836,968 with Prime Factorization
| 2 | 218, 407, 836, 968 |
| 2 | 109, 407, 418, 484 |
| 11 | 109, 407, 209, 242 |
| 109, 37, 19, 22 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 11 x 109 x 37 x 19 x 22 = 74174936
Therefore, the lowest common multiple of 218,407,836,968 is 74174936.
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 407 x 836 x 968 = 71801338048
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
407 : 1, 11, 37, 407
836 : 1, 2, 4, 11, 19, 22, 38, 44, 76, 209, 418, 836
968 : 1, 2, 4, 8, 11, 22, 44, 88, 121, 242, 484, 968
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 218,407,836,968, is 1.
Now, the common factors can be found like this.
218:2x 109
407:11x 37
836:2x 2x 11x 19
968:2x 2x 2x 11x 11
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 = 71801338048/(1x968)
LCM = 71801338048/968
LCM = 74174936
Thus, we can understand that the LCM of 218,407,836,968 is 74174936.
