Given numbers are 900,390,262,381,861
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 900,390,262,381,861 is 55865382300.
Find LCM of 900,390,262,381,861 with Prime Factorization
| 2 | 900, 390, 262, 381, 861 |
| 3 | 450, 195, 131, 381, 861 |
| 5 | 150, 65, 131, 127, 287 |
| 30, 13, 131, 127, 287 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 30 x 13 x 131 x 127 x 287 = 55865382300
Therefore, the lowest common multiple of 900,390,262,381,861 is 55865382300.
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.
900 x 390 x 262 x 381 x 861 = 30167306442000
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.
900 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 25, 30, 36, 45, 50, 60, 75, 90, 100, 150, 180, 225, 300, 450, 900
390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390
262 : 1, 2, 131, 262
381 : 1, 3, 127, 381
861 : 1, 3, 7, 21, 41, 123, 287, 861
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 900,390,262,381,861, is 1.
Now, the common factors can be found like this.
900:2x 2x 3x 3x 5x 5
390:2x 3x 5x 13
262:2x 131
381:3x 127
861:3x 7x 41
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 3x 3x 3x 5 = 540
Therefore, the value for common factors is 540.
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 = 30167306442000/(1x540)
LCM = 30167306442000/540
LCM = 55865382300
Thus, we can understand that the LCM of 900,390,262,381,861 is 55865382300.
