Given numbers are 421,916,786,964,107
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 421,916,786,964,107 is 3908147444076.
Find LCM of 421,916,786,964,107 with Prime Factorization
| 2 | 421, 916, 786, 964, 107 |
| 2 | 421, 458, 393, 482, 107 |
| 421, 229, 393, 241, 107 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 421 x 229 x 393 x 241 x 107 = 3908147444076
Therefore, the lowest common multiple of 421,916,786,964,107 is 3908147444076.
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.
421 x 916 x 786 x 964 x 107 = 31265179552608
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.
421 : 1, 421
916 : 1, 2, 4, 229, 458, 916
786 : 1, 2, 3, 6, 131, 262, 393, 786
964 : 1, 2, 4, 241, 482, 964
107 : 1, 107
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 421,916,786,964,107, is 1.
Now, the common factors can be found like this.
421:421
916:2x 2x 229
786:2x 3x 131
964:2x 2x 241
107:107
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 2 = 8
Therefore, the value for common factors is 8.
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 = 31265179552608/(1x8)
LCM = 31265179552608/8
LCM = 3908147444076
Thus, we can understand that the LCM of 421,916,786,964,107 is 3908147444076.
