Given numbers are 747,905,351,157,451
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 747,905,351,157,451 is 1866852399555.
Find LCM of 747,905,351,157,451 with Prime Factorization
| 3 | 747, 905, 351, 157, 451 |
| 3 | 249, 905, 117, 157, 451 |
| 83, 905, 39, 157, 451 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 83 x 905 x 39 x 157 x 451 = 1866852399555
Therefore, the lowest common multiple of 747,905,351,157,451 is 1866852399555.
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.
747 x 905 x 351 x 157 x 451 = 16801671595995
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.
747 : 1, 3, 9, 83, 249, 747
905 : 1, 5, 181, 905
351 : 1, 3, 9, 13, 27, 39, 117, 351
157 : 1, 157
451 : 1, 11, 41, 451
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 747,905,351,157,451, is 1.
Now, the common factors can be found like this.
747:3x 3x 83
905:5x 181
351:3x 3x 3x 13
157:157
451:11x 41
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3 = 9
Therefore, the value for common factors is 9.
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 = 16801671595995/(1x9)
LCM = 16801671595995/9
LCM = 1866852399555
Thus, we can understand that the LCM of 747,905,351,157,451 is 1866852399555.
