Given numbers are 856,630,990,522
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 856,630,990,522 is 86015160.
Find LCM of 856,630,990,522 with Prime Factorization
| 2 | 856, 630, 990, 522 |
| 3 | 428, 315, 495, 261 |
| 3 | 428, 105, 165, 87 |
| 5 | 428, 35, 55, 29 |
| 428, 7, 11, 29 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 5 x 428 x 7 x 11 x 29 = 86015160
Therefore, the lowest common multiple of 856,630,990,522 is 86015160.
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.
856 x 630 x 990 x 522 = 278689118400
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.
856 : 1, 2, 4, 8, 107, 214, 428, 856
630 : 1, 2, 3, 5, 6, 7, 9, 10, 14, 15, 18, 21, 30, 35, 42, 45, 63, 70, 90, 105, 126, 210, 315, 630
990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990
522 : 1, 2, 3, 6, 9, 18, 29, 58, 87, 174, 261, 522
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 856,630,990,522, is 2.
Now, the common factors can be found like this.
856:2x 2x 2x 107
630:2x 3x 3x 5x 7
990:2x 3x 3x 5x 11
522:2x 3x 3x 29
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 3x 5 = 1620
Therefore, the value for common factors is 1620.
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 = 278689118400/(2x1620)
LCM = 278689118400/3240
LCM = 86015160
Thus, we can understand that the LCM of 856,630,990,522 is 86015160.
