Given numbers are 615,921,428,293,879
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 615,921,428,293,879 is 23676902220.
Find LCM of 615,921,428,293,879 with Prime Factorization
| 3 | 615, 921, 428, 293, 879 |
| 293 | 205, 307, 428, 293, 293 |
| 205, 307, 428, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
3 x 293 x 205 x 307 x 428 x 1 x 1 = 23676902220
Therefore, the lowest common multiple of 615,921,428,293,879 is 23676902220.
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 921 x 428 x 293 x 879 = 62435991154140
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
921 : 1, 3, 307, 921
428 : 1, 2, 4, 107, 214, 428
293 : 1, 293
879 : 1, 3, 293, 879
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 615,921,428,293,879, is 1.
Now, the common factors can be found like this.
615:3x 5x 41
921:3x 307
428:2x 2x 107
293:293
879:3x 293
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 293 = 2637
Therefore, the value for common factors is 2637.
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 = 62435991154140/(1x2637)
LCM = 62435991154140/2637
LCM = 23676902220
Thus, we can understand that the LCM of 615,921,428,293,879 is 23676902220.
