Given numbers are 615,492,646,359
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 615,492,646,359 is 285254220.
Find LCM of 615,492,646,359 with Prime Factorization
| 2 | 615, 492, 646, 359 |
| 3 | 615, 246, 323, 359 |
| 41 | 205, 82, 323, 359 |
| 5, 2, 323, 359 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 41 x 5 x 2 x 323 x 359 = 285254220
Therefore, the lowest common multiple of 615,492,646,359 is 285254220.
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 492 x 646 x 359 = 70172538120
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
492 : 1, 2, 3, 4, 6, 12, 41, 82, 123, 164, 246, 492
646 : 1, 2, 17, 19, 34, 38, 323, 646
359 : 1, 359
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 615,492,646,359, is 1.
Now, the common factors can be found like this.
615:3x 5x 41
492:2x 2x 3x 41
646:2x 17x 19
359:359
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 41 = 246
Therefore, the value for common factors is 246.
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 = 70172538120/(1x246)
LCM = 70172538120/246
LCM = 285254220
Thus, we can understand that the LCM of 615,492,646,359 is 285254220.
