Given numbers are 146,646,974,618,309
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 146,646,974,618,309 is 7096477314.
Find LCM of 146,646,974,618,309 with Prime Factorization
| 2 | 146, 646, 974, 618, 309 |
| 3 | 73, 323, 487, 309, 309 |
| 103 | 73, 323, 487, 103, 103 |
| 73, 323, 487, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 103 x 73 x 323 x 487 x 1 x 1 = 7096477314
Therefore, the lowest common multiple of 146,646,974,618,309 is 7096477314.
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.
146 x 646 x 974 x 618 x 309 = 17542491920208
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.
146 : 1, 2, 73, 146
646 : 1, 2, 17, 19, 34, 38, 323, 646
974 : 1, 2, 487, 974
618 : 1, 2, 3, 6, 103, 206, 309, 618
309 : 1, 3, 103, 309
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 146,646,974,618,309, is 1.
Now, the common factors can be found like this.
146:2x 73
646:2x 17x 19
974:2x 487
618:2x 3x 103
309:3x 103
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 3x 103 = 2472
Therefore, the value for common factors is 2472.
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 = 17542491920208/(1x2472)
LCM = 17542491920208/2472
LCM = 7096477314
Thus, we can understand that the LCM of 146,646,974,618,309 is 7096477314.
