Given numbers are 471,902,471,138
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 471,902,471,138 is 9771366.
Find LCM of 471,902,471,138 with Prime Factorization
| 2 | 471, 902, 471, 138 |
| 3 | 471, 451, 471, 69 |
| 157 | 157, 451, 157, 23 |
| 1, 451, 1, 23 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 157 x 1 x 451 x 1 x 23 = 9771366
Therefore, the lowest common multiple of 471,902,471,138 is 9771366.
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.
471 x 902 x 471 x 138 = 27613880316
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.
471 : 1, 3, 157, 471
902 : 1, 2, 11, 22, 41, 82, 451, 902
471 : 1, 3, 157, 471
138 : 1, 2, 3, 6, 23, 46, 69, 138
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 471,902,471,138, is 1.
Now, the common factors can be found like this.
471:3x 157
902:2x 11x 41
471:3x 157
138:2x 3x 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 3x 3x 157 = 2826
Therefore, the value for common factors is 2826.
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 = 27613880316/(1x2826)
LCM = 27613880316/2826
LCM = 9771366
Thus, we can understand that the LCM of 471,902,471,138 is 9771366.
