Given numbers are 218,649,106,118
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 218,649,106,118 is 7498546.
Find LCM of 218,649,106,118 with Prime Factorization
| 2 | 218, 649, 106, 118 |
| 59 | 109, 649, 53, 59 |
| 109, 11, 53, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 59 x 109 x 11 x 53 x 1 = 7498546
Therefore, the lowest common multiple of 218,649,106,118 is 7498546.
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 649 x 106 x 118 = 1769656856
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
649 : 1, 11, 59, 649
106 : 1, 2, 53, 106
118 : 1, 2, 59, 118
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 218,649,106,118, is 1.
Now, the common factors can be found like this.
218:2x 109
649:11x 59
106:2x 53
118:2x 59
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 59 = 236
Therefore, the value for common factors is 236.
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 = 1769656856/(1x236)
LCM = 1769656856/236
LCM = 7498546
Thus, we can understand that the LCM of 218,649,106,118 is 7498546.
