Given numbers are 148,690,992,399,779
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 148,690,992,399,779 is 69050684640.
Find LCM of 148,690,992,399,779 with Prime Factorization
| 2 | 148, 690, 992, 399, 779 |
| 2 | 74, 345, 496, 399, 779 |
| 3 | 37, 345, 248, 399, 779 |
| 19 | 37, 115, 248, 133, 779 |
| 37, 115, 248, 7, 41 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 19 x 37 x 115 x 248 x 7 x 41 = 69050684640
Therefore, the lowest common multiple of 148,690,992,399,779 is 69050684640.
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.
148 x 690 x 992 x 399 x 779 = 31487112195840
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.
148 : 1, 2, 4, 37, 74, 148
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
992 : 1, 2, 4, 8, 16, 31, 32, 62, 124, 248, 496, 992
399 : 1, 3, 7, 19, 21, 57, 133, 399
779 : 1, 19, 41, 779
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 148,690,992,399,779, is 1.
Now, the common factors can be found like this.
148:2x 2x 37
690:2x 3x 5x 23
992:2x 2x 2x 2x 2x 31
399:3x 7x 19
779:19x 41
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 2x 3x 19 = 456
Therefore, the value for common factors is 456.
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 = 31487112195840/(1x456)
LCM = 31487112195840/456
LCM = 69050684640
Thus, we can understand that the LCM of 148,690,992,399,779 is 69050684640.
