Given numbers are 875,890,671,864,161
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 875,890,671,864,161 is 1038393972000.
Find LCM of 875,890,671,864,161 with Prime Factorization
| 2 | 875, 890, 671, 864, 161 |
| 5 | 875, 445, 671, 432, 161 |
| 7 | 175, 89, 671, 432, 161 |
| 25, 89, 671, 432, 23 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 7 x 25 x 89 x 671 x 432 x 23 = 1038393972000
Therefore, the lowest common multiple of 875,890,671,864,161 is 1038393972000.
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.
875 x 890 x 671 x 864 x 161 = 72687578040000
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.
875 : 1, 5, 7, 25, 35, 125, 175, 875
890 : 1, 2, 5, 10, 89, 178, 445, 890
671 : 1, 11, 61, 671
864 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 32, 36, 48, 54, 72, 96, 108, 144, 216, 288, 432, 864
161 : 1, 7, 23, 161
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 875,890,671,864,161, is 1.
Now, the common factors can be found like this.
875:5x 5x 5x 7
890:2x 5x 89
671:11x 61
864:2x 2x 2x 2x 2x 3x 3x 3
161:7x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 7 = 70
Therefore, the value for common factors is 70.
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 = 72687578040000/(1x70)
LCM = 72687578040000/70
LCM = 1038393972000
Thus, we can understand that the LCM of 875,890,671,864,161 is 1038393972000.
