Given numbers are 872,391,225,772,956
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 872,391,225,772,956 is 3538595903400.
Find LCM of 872,391,225,772,956 with Prime Factorization
| 2 | 872, 391, 225, 772, 956 |
| 2 | 436, 391, 225, 386, 478 |
| 218, 391, 225, 193, 239 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 218 x 391 x 225 x 193 x 239 = 3538595903400
Therefore, the lowest common multiple of 872,391,225,772,956 is 3538595903400.
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.
872 x 391 x 225 x 772 x 956 = 56617534454400
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.
872 : 1, 2, 4, 8, 109, 218, 436, 872
391 : 1, 17, 23, 391
225 : 1, 3, 5, 9, 15, 25, 45, 75, 225
772 : 1, 2, 4, 193, 386, 772
956 : 1, 2, 4, 239, 478, 956
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 872,391,225,772,956, is 1.
Now, the common factors can be found like this.
872:2x 2x 2x 109
391:17x 23
225:3x 3x 5x 5
772:2x 2x 193
956:2x 2x 239
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 2 = 16
Therefore, the value for common factors is 16.
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 = 56617534454400/(1x16)
LCM = 56617534454400/16
LCM = 3538595903400
Thus, we can understand that the LCM of 872,391,225,772,956 is 3538595903400.
