Given numbers are 870,338,554,865,280
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 870,338,554,865,280 is 197283089640.
Find LCM of 870,338,554,865,280 with Prime Factorization
| 2 | 870, 338, 554, 865, 280 |
| 5 | 435, 169, 277, 865, 140 |
| 87, 169, 277, 173, 28 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 87 x 169 x 277 x 173 x 28 = 197283089640
Therefore, the lowest common multiple of 870,338,554,865,280 is 197283089640.
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.
870 x 338 x 554 x 865 x 280 = 39456617928000
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.
870 : 1, 2, 3, 5, 6, 10, 15, 29, 30, 58, 87, 145, 174, 290, 435, 870
338 : 1, 2, 13, 26, 169, 338
554 : 1, 2, 277, 554
865 : 1, 5, 173, 865
280 : 1, 2, 4, 5, 7, 8, 10, 14, 20, 28, 35, 40, 56, 70, 140, 280
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 870,338,554,865,280, is 1.
Now, the common factors can be found like this.
870:2x 3x 5x 29
338:2x 13x 13
554:2x 277
865:5x 173
280:2x 2x 2x 5x 7
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 5x 5 = 200
Therefore, the value for common factors is 200.
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 = 39456617928000/(1x200)
LCM = 39456617928000/200
LCM = 197283089640
Thus, we can understand that the LCM of 870,338,554,865,280 is 197283089640.
