Given numbers are 813,122,551,862
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 813,122,551,862 is 23554790466.
Find LCM of 813,122,551,862 with Prime Factorization
| 2 | 813, 122, 551, 862 |
| 813, 61, 551, 431 |
Multiply the prime numbers at the bottom and the left side.
2 x 813 x 61 x 551 x 431 = 23554790466
Therefore, the lowest common multiple of 813,122,551,862 is 23554790466.
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.
813 x 122 x 551 x 862 = 47109580932
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.
813 : 1, 3, 271, 813
122 : 1, 2, 61, 122
551 : 1, 19, 29, 551
862 : 1, 2, 431, 862
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 813,122,551,862, is 1.
Now, the common factors can be found like this.
813:3x 271
122:2x 61
551:19x 29
862:2x 431
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2 = 2
Therefore, the value for common factors is 2.
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 = 47109580932/(1x2)
LCM = 47109580932/2
LCM = 23554790466
Thus, we can understand that the LCM of 813,122,551,862 is 23554790466.
