Given numbers are 191,989,639,801
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 191,989,639,801 is 10742875029.
Find LCM of 191,989,639,801 with Prime Factorization
| 3 | 191, 989, 639, 801 |
| 3 | 191, 989, 213, 267 |
| 191, 989, 71, 89 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 191 x 989 x 71 x 89 = 10742875029
Therefore, the lowest common multiple of 191,989,639,801 is 10742875029.
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.
191 x 989 x 639 x 801 = 96685875261
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.
191 : 1, 191
989 : 1, 23, 43, 989
639 : 1, 3, 9, 71, 213, 639
801 : 1, 3, 9, 89, 267, 801
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 191,989,639,801, is 1.
Now, the common factors can be found like this.
191:191
989:23x 43
639:3x 3x 71
801:3x 3x 89
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3 = 9
Therefore, the value for common factors is 9.
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 = 96685875261/(1x9)
LCM = 96685875261/9
LCM = 10742875029
Thus, we can understand that the LCM of 191,989,639,801 is 10742875029.
