Given numbers are 278,992,945,627,290
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 278,992,945,627,290 is 789773513760.
Find LCM of 278,992,945,627,290 with Prime Factorization
| 2 | 278, 992, 945, 627, 290 |
| 3 | 139, 496, 945, 627, 145 |
| 5 | 139, 496, 315, 209, 145 |
| 139, 496, 63, 209, 29 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 139 x 496 x 63 x 209 x 29 = 789773513760
Therefore, the lowest common multiple of 278,992,945,627,290 is 789773513760.
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.
278 x 992 x 945 x 627 x 290 = 47386410825600
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.
278 : 1, 2, 139, 278
992 : 1, 2, 4, 8, 16, 31, 32, 62, 124, 248, 496, 992
945 : 1, 3, 5, 7, 9, 15, 21, 27, 35, 45, 63, 105, 135, 189, 315, 945
627 : 1, 3, 11, 19, 33, 57, 209, 627
290 : 1, 2, 5, 10, 29, 58, 145, 290
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 278,992,945,627,290, is 1.
Now, the common factors can be found like this.
278:2x 139
992:2x 2x 2x 2x 2x 31
945:3x 3x 3x 5x 7
627:3x 11x 19
290:2x 5x 29
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 3x 5 = 60
Therefore, the value for common factors is 60.
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 = 47386410825600/(1x60)
LCM = 47386410825600/60
LCM = 789773513760
Thus, we can understand that the LCM of 278,992,945,627,290 is 789773513760.
