Given numbers are 354,979,649,389
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 354,979,649,389 is 134814174.
Find LCM of 354,979,649,389 with Prime Factorization
| 11 | 354, 979, 649, 389 |
| 59 | 354, 89, 59, 389 |
| 6, 89, 1, 389 |
Multiply the prime numbers at the bottom and the left side.
11 x 59 x 6 x 89 x 1 x 389 = 134814174
Therefore, the lowest common multiple of 354,979,649,389 is 134814174.
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.
354 x 979 x 649 x 389 = 87494398926
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.
354 : 1, 2, 3, 6, 59, 118, 177, 354
979 : 1, 11, 89, 979
649 : 1, 11, 59, 649
389 : 1, 389
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 354,979,649,389, is 1.
Now, the common factors can be found like this.
354:2x 3x 59
979:11x 89
649:11x 59
389:389
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
11x 59 = 649
Therefore, the value for common factors is 649.
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 = 87494398926/(1x649)
LCM = 87494398926/649
LCM = 134814174
Thus, we can understand that the LCM of 354,979,649,389 is 134814174.
