Given numbers are 810,875,912,889
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 810,875,912,889 is 2736342000.
Find LCM of 810,875,912,889 with Prime Factorization
| 2 | 810, 875, 912, 889 |
| 3 | 405, 875, 456, 889 |
| 5 | 135, 875, 152, 889 |
| 7 | 27, 175, 152, 889 |
| 27, 25, 152, 127 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 7 x 27 x 25 x 152 x 127 = 2736342000
Therefore, the lowest common multiple of 810,875,912,889 is 2736342000.
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.
810 x 875 x 912 x 889 = 574631820000
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.
810 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 81, 90, 135, 162, 270, 405, 810
875 : 1, 5, 7, 25, 35, 125, 175, 875
912 : 1, 2, 3, 4, 6, 8, 12, 16, 19, 24, 38, 48, 57, 76, 114, 152, 228, 304, 456, 912
889 : 1, 7, 127, 889
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 810,875,912,889, is 1.
Now, the common factors can be found like this.
810:2x 3x 3x 3x 3x 5
875:5x 5x 5x 7
912:2x 2x 2x 2x 3x 19
889:7x 127
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 5x 7 = 210
Therefore, the value for common factors is 210.
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 = 574631820000/(1x210)
LCM = 574631820000/210
LCM = 2736342000
Thus, we can understand that the LCM of 810,875,912,889 is 2736342000.
