Given numbers are 294,311,989,814,861
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 294,311,989,814,861 is 1508975807262.
Find LCM of 294,311,989,814,861 with Prime Factorization
| 2 | 294, 311, 989, 814, 861 |
| 3 | 147, 311, 989, 407, 861 |
| 7 | 49, 311, 989, 407, 287 |
| 7, 311, 989, 407, 41 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 7 x 311 x 989 x 407 x 41 = 1508975807262
Therefore, the lowest common multiple of 294,311,989,814,861 is 1508975807262.
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.
294 x 311 x 989 x 814 x 861 = 63376983905004
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.
294 : 1, 2, 3, 6, 7, 14, 21, 42, 49, 98, 147, 294
311 : 1, 311
989 : 1, 23, 43, 989
814 : 1, 2, 11, 22, 37, 74, 407, 814
861 : 1, 3, 7, 21, 41, 123, 287, 861
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 294,311,989,814,861, is 1.
Now, the common factors can be found like this.
294:2x 3x 7x 7
311:311
989:23x 43
814:2x 11x 37
861:3x 7x 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 3x 7 = 42
Therefore, the value for common factors is 42.
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 = 63376983905004/(1x42)
LCM = 63376983905004/42
LCM = 1508975807262
Thus, we can understand that the LCM of 294,311,989,814,861 is 1508975807262.
