Given numbers are 852,908,681,840
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 852,908,681,840 is 13538280.
Find LCM of 852,908,681,840 with Prime Factorization
| 2 | 852, 908, 681, 840 |
| 2 | 426, 454, 681, 420 |
| 3 | 213, 227, 681, 210 |
| 227 | 71, 227, 227, 70 |
| 71, 1, 1, 70 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 227 x 71 x 1 x 1 x 70 = 13538280
Therefore, the lowest common multiple of 852,908,681,840 is 13538280.
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.
852 x 908 x 681 x 840 = 442539296640
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.
852 : 1, 2, 3, 4, 6, 12, 71, 142, 213, 284, 426, 852
908 : 1, 2, 4, 227, 454, 908
681 : 1, 3, 227, 681
840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 852,908,681,840, is 1.
Now, the common factors can be found like this.
852:2x 2x 3x 71
908:2x 2x 227
681:3x 227
840:2x 2x 2x 3x 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 2x 3x 3x 227 = 32688
Therefore, the value for common factors is 32688.
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 = 442539296640/(1x32688)
LCM = 442539296640/32688
LCM = 13538280
Thus, we can understand that the LCM of 852,908,681,840 is 13538280.
