Given numbers are 281,968,374,782
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 281,968,374,782 is 106355128.
Find LCM of 281,968,374,782 with Prime Factorization
| 2 | 281, 968, 374, 782 |
| 11 | 281, 484, 187, 391 |
| 17 | 281, 44, 17, 391 |
| 281, 44, 1, 23 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 17 x 281 x 44 x 1 x 23 = 106355128
Therefore, the lowest common multiple of 281,968,374,782 is 106355128.
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.
281 x 968 x 374 x 782 = 79553635744
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.
281 : 1, 281
968 : 1, 2, 4, 8, 11, 22, 44, 88, 121, 242, 484, 968
374 : 1, 2, 11, 17, 22, 34, 187, 374
782 : 1, 2, 17, 23, 34, 46, 391, 782
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 281,968,374,782, is 1.
Now, the common factors can be found like this.
281:281
968:2x 2x 2x 11x 11
374:2x 11x 17
782:2x 17x 23
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 11x 17 = 748
Therefore, the value for common factors is 748.
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 = 79553635744/(1x748)
LCM = 79553635744/748
LCM = 106355128
Thus, we can understand that the LCM of 281,968,374,782 is 106355128.
