Given numbers are 418,813,978,688,148
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 418,813,978,688,148 is 705041365776.
Find LCM of 418,813,978,688,148 with Prime Factorization
| 2 | 418, 813, 978, 688, 148 |
| 2 | 209, 813, 489, 344, 74 |
| 3 | 209, 813, 489, 172, 37 |
| 209, 271, 163, 172, 37 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 209 x 271 x 163 x 172 x 37 = 705041365776
Therefore, the lowest common multiple of 418,813,978,688,148 is 705041365776.
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.
418 x 813 x 978 x 688 x 148 = 33841985557248
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.
418 : 1, 2, 11, 19, 22, 38, 209, 418
813 : 1, 3, 271, 813
978 : 1, 2, 3, 6, 163, 326, 489, 978
688 : 1, 2, 4, 8, 16, 43, 86, 172, 344, 688
148 : 1, 2, 4, 37, 74, 148
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 418,813,978,688,148, is 1.
Now, the common factors can be found like this.
418:2x 11x 19
813:3x 271
978:2x 3x 163
688:2x 2x 2x 2x 43
148:2x 2x 37
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 2x 3 = 48
Therefore, the value for common factors is 48.
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 = 33841985557248/(1x48)
LCM = 33841985557248/48
LCM = 705041365776
Thus, we can understand that the LCM of 418,813,978,688,148 is 705041365776.
