Given numbers are 959,649,638,819
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 959,649,638,819 is 4223545326.
Find LCM of 959,649,638,819 with Prime Factorization
| 7 | 959, 649, 638, 819 |
| 11 | 137, 649, 638, 117 |
| 137, 59, 58, 117 |
Multiply the prime numbers at the bottom and the left side.
7 x 11 x 137 x 59 x 58 x 117 = 4223545326
Therefore, the lowest common multiple of 959,649,638,819 is 4223545326.
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.
959 x 649 x 638 x 819 = 325212990102
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.
959 : 1, 7, 137, 959
649 : 1, 11, 59, 649
638 : 1, 2, 11, 22, 29, 58, 319, 638
819 : 1, 3, 7, 9, 13, 21, 39, 63, 91, 117, 273, 819
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 959,649,638,819, is 1.
Now, the common factors can be found like this.
959:7x 137
649:11x 59
638:2x 11x 29
819:3x 3x 7x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
7x 11 = 77
Therefore, the value for common factors is 77.
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 = 325212990102/(1x77)
LCM = 325212990102/77
LCM = 4223545326
Thus, we can understand that the LCM of 959,649,638,819 is 4223545326.
