Given numbers are 939,403,894,242
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 939,403,894,242 is 13644960186.
Find LCM of 939,403,894,242 with Prime Factorization
| 2 | 939, 403, 894, 242 |
| 3 | 939, 403, 447, 121 |
| 313, 403, 149, 121 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 313 x 403 x 149 x 121 = 13644960186
Therefore, the lowest common multiple of 939,403,894,242 is 13644960186.
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.
939 x 403 x 894 x 242 = 81869761116
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.
939 : 1, 3, 313, 939
403 : 1, 13, 31, 403
894 : 1, 2, 3, 6, 149, 298, 447, 894
242 : 1, 2, 11, 22, 121, 242
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 939,403,894,242, is 1.
Now, the common factors can be found like this.
939:3x 313
403:13x 31
894:2x 3x 149
242:2x 11x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3 = 6
Therefore, the value for common factors is 6.
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 = 81869761116/(1x6)
LCM = 81869761116/6
LCM = 13644960186
Thus, we can understand that the LCM of 939,403,894,242 is 13644960186.
