Given numbers are 872,874,896,487
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 872,874,896,487 is 20784754816.
Find LCM of 872,874,896,487 with Prime Factorization
2 | 872, 874, 896, 487 |
2 | 436, 437, 448, 487 |
2 | 218, 437, 224, 487 |
109, 437, 112, 487 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 109 x 437 x 112 x 487 = 20784754816
Therefore, the lowest common multiple of 872,874,896,487 is 20784754816.
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 874 x 896 x 487 = 332556077056
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
874 : 1, 2, 19, 23, 38, 46, 437, 874
896 : 1, 2, 4, 7, 8, 14, 16, 28, 32, 56, 64, 112, 128, 224, 448, 896
487 : 1, 487
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 872,874,896,487, is 1.
Now, the common factors can be found like this.
872:2x 2x 2x 109
874:2x 19x 23
896:2x 2x 2x 2x 2x 2x 2x 7
487:487
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 = 332556077056/(1x16)
LCM = 332556077056/16
LCM = 20784754816
Thus, we can understand that the LCM of 872,874,896,487 is 20784754816.
