Given numbers are 946,905,744,268,172
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 946,905,744,268,172 is 21338184120.
Find LCM of 946,905,744,268,172 with Prime Factorization
| 2 | 946, 905, 744, 268, 172 |
| 2 | 473, 905, 372, 134, 86 |
| 43 | 473, 905, 186, 67, 43 |
| 11, 905, 186, 67, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 43 x 11 x 905 x 186 x 67 x 1 = 21338184120
Therefore, the lowest common multiple of 946,905,744,268,172 is 21338184120.
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.
946 x 905 x 744 x 268 x 172 = 29361341349120
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.
946 : 1, 2, 11, 22, 43, 86, 473, 946
905 : 1, 5, 181, 905
744 : 1, 2, 3, 4, 6, 8, 12, 24, 31, 62, 93, 124, 186, 248, 372, 744
268 : 1, 2, 4, 67, 134, 268
172 : 1, 2, 4, 43, 86, 172
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 946,905,744,268,172, is 1.
Now, the common factors can be found like this.
946:2x 11x 43
905:5x 181
744:2x 2x 2x 3x 31
268:2x 2x 67
172:2x 2x 43
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 2x 43 = 1376
Therefore, the value for common factors is 1376.
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 = 29361341349120/(1x1376)
LCM = 29361341349120/1376
LCM = 21338184120
Thus, we can understand that the LCM of 946,905,744,268,172 is 21338184120.
