Given numbers are 916,394,976,940,390
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 916,394,976,940,390 is 403537589520.
Find LCM of 916,394,976,940,390 with Prime Factorization
| 2 | 916, 394, 976, 940, 390 |
| 2 | 458, 197, 488, 470, 195 |
| 5 | 229, 197, 244, 235, 195 |
| 229, 197, 244, 47, 39 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 229 x 197 x 244 x 47 x 39 = 403537589520
Therefore, the lowest common multiple of 916,394,976,940,390 is 403537589520.
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.
916 x 394 x 976 x 940 x 390 = 129132028646400
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.
916 : 1, 2, 4, 229, 458, 916
394 : 1, 2, 197, 394
976 : 1, 2, 4, 8, 16, 61, 122, 244, 488, 976
940 : 1, 2, 4, 5, 10, 20, 47, 94, 188, 235, 470, 940
390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 916,394,976,940,390, is 2.
Now, the common factors can be found like this.
916:2x 2x 229
394:2x 197
976:2x 2x 2x 2x 61
940:2x 2x 5x 47
390:2x 3x 5x 13
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 2x 2x 5 = 160
Therefore, the value for common factors is 160.
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 = 129132028646400/(2x160)
LCM = 129132028646400/320
LCM = 403537589520
Thus, we can understand that the LCM of 916,394,976,940,390 is 403537589520.
