Given numbers are 418,649,814,804,978
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 418,649,814,804,978 is 59792081844.
Find LCM of 418,649,814,804,978 with Prime Factorization
| 2 | 418, 649, 814, 804, 978 |
| 3 | 209, 649, 407, 402, 489 |
| 11 | 209, 649, 407, 134, 163 |
| 19, 59, 37, 134, 163 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 19 x 59 x 37 x 134 x 163 = 59792081844
Therefore, the lowest common multiple of 418,649,814,804,978 is 59792081844.
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 649 x 814 x 804 x 978 = 173636205674976
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
649 : 1, 11, 59, 649
814 : 1, 2, 11, 22, 37, 74, 407, 814
804 : 1, 2, 3, 4, 6, 12, 67, 134, 201, 268, 402, 804
978 : 1, 2, 3, 6, 163, 326, 489, 978
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 418,649,814,804,978, is 1.
Now, the common factors can be found like this.
418:2x 11x 19
649:11x 59
814:2x 11x 37
804:2x 2x 3x 67
978:2x 3x 163
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 3x 11x 11 = 2904
Therefore, the value for common factors is 2904.
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 = 173636205674976/(1x2904)
LCM = 173636205674976/2904
LCM = 59792081844
Thus, we can understand that the LCM of 418,649,814,804,978 is 59792081844.
