Given numbers are 578,876,867,620
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 578,876,867,620 is 39240420.
Find LCM of 578,876,867,620 with Prime Factorization
| 2 | 578, 876, 867, 620 |
| 2 | 289, 438, 867, 310 |
| 3 | 289, 219, 867, 155 |
| 17 | 289, 73, 289, 155 |
| 17 | 17, 73, 17, 155 |
| 1, 73, 1, 155 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 17 x 17 x 1 x 73 x 1 x 155 = 39240420
Therefore, the lowest common multiple of 578,876,867,620 is 39240420.
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.
578 x 876 x 867 x 620 = 272171553120
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.
578 : 1, 2, 17, 34, 289, 578
876 : 1, 2, 3, 4, 6, 12, 73, 146, 219, 292, 438, 876
867 : 1, 3, 17, 51, 289, 867
620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 578,876,867,620, is 1.
Now, the common factors can be found like this.
578:2x 17x 17
876:2x 2x 3x 73
867:3x 17x 17
620:2x 2x 5x 31
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 17x 17 = 6936
Therefore, the value for common factors is 6936.
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 = 272171553120/(1x6936)
LCM = 272171553120/6936
LCM = 39240420
Thus, we can understand that the LCM of 578,876,867,620 is 39240420.
