Given numbers are 915,139,793,278
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 915,139,793,278 is 3306810.
Find LCM of 915,139,793,278 with Prime Factorization
| 61 | 915, 139, 793, 278 |
| 139 | 15, 139, 13, 278 |
| 15, 1, 13, 2 |
Multiply the prime numbers at the bottom and the left side.
61 x 139 x 15 x 1 x 13 x 2 = 3306810
Therefore, the lowest common multiple of 915,139,793,278 is 3306810.
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.
915 x 139 x 793 x 278 = 28038441990
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.
915 : 1, 3, 5, 15, 61, 183, 305, 915
139 : 1, 139
793 : 1, 13, 61, 793
278 : 1, 2, 139, 278
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 915,139,793,278, is 1.
Now, the common factors can be found like this.
915:3x 5x 61
139:139
793:13x 61
278:2x 139
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
61x 139 = 8479
Therefore, the value for common factors is 8479.
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 = 28038441990/(1x8479)
LCM = 28038441990/8479
LCM = 3306810
Thus, we can understand that the LCM of 915,139,793,278 is 3306810.
