Given numbers are 615,666,778,195,251
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 615,666,778,195,251 is 173298484710.
Find LCM of 615,666,778,195,251 with Prime Factorization
| 2 | 615, 666, 778, 195, 251 |
| 3 | 615, 333, 389, 195, 251 |
| 5 | 205, 111, 389, 65, 251 |
| 41, 111, 389, 13, 251 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 41 x 111 x 389 x 13 x 251 = 173298484710
Therefore, the lowest common multiple of 615,666,778,195,251 is 173298484710.
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.
615 x 666 x 778 x 195 x 251 = 15596863623900
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.
615 : 1, 3, 5, 15, 41, 123, 205, 615
666 : 1, 2, 3, 6, 9, 18, 37, 74, 111, 222, 333, 666
778 : 1, 2, 389, 778
195 : 1, 3, 5, 13, 15, 39, 65, 195
251 : 1, 251
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 615,666,778,195,251, is 1.
Now, the common factors can be found like this.
615:3x 5x 41
666:2x 3x 3x 37
778:2x 389
195:3x 5x 13
251:251
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 3x 5 = 90
Therefore, the value for common factors is 90.
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 = 15596863623900/(1x90)
LCM = 15596863623900/90
LCM = 173298484710
Thus, we can understand that the LCM of 615,666,778,195,251 is 173298484710.
