Given numbers are 211,638,146,968
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 211,638,146,968 is 432393016.
Find LCM of 211,638,146,968 with Prime Factorization
| 2 | 211, 638, 146, 968 |
| 11 | 211, 319, 73, 484 |
| 211, 29, 73, 44 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 211 x 29 x 73 x 44 = 432393016
Therefore, the lowest common multiple of 211,638,146,968 is 432393016.
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.
211 x 638 x 146 x 968 = 19025292704
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.
211 : 1, 211
638 : 1, 2, 11, 22, 29, 58, 319, 638
146 : 1, 2, 73, 146
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 211,638,146,968, is 1.
Now, the common factors can be found like this.
211:211
638:2x 11x 29
146:2x 73
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 11 = 44
Therefore, the value for common factors is 44.
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 = 19025292704/(1x44)
LCM = 19025292704/44
LCM = 432393016
Thus, we can understand that the LCM of 211,638,146,968 is 432393016.
