Given numbers are 107,921,989,162
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 107,921,989,162 is 5263001082.
Find LCM of 107,921,989,162 with Prime Factorization
| 3 | 107, 921, 989, 162 |
| 107, 307, 989, 54 |
Multiply the prime numbers at the bottom and the left side.
3 x 107 x 307 x 989 x 54 = 5263001082
Therefore, the lowest common multiple of 107,921,989,162 is 5263001082.
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.
107 x 921 x 989 x 162 = 15789003246
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.
107 : 1, 107
921 : 1, 3, 307, 921
989 : 1, 23, 43, 989
162 : 1, 2, 3, 6, 9, 18, 27, 54, 81, 162
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 107,921,989,162, is 1.
Now, the common factors can be found like this.
107:107
921:3x 307
989:23x 43
162:2x 3x 3x 3x 3
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3 = 3
Therefore, the value for common factors is 3.
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 = 15789003246/(1x3)
LCM = 15789003246/3
LCM = 5263001082
Thus, we can understand that the LCM of 107,921,989,162 is 5263001082.
