Given numbers are 760,910,935,670,405
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 760,910,935,670,405 is 70186956840.
Find LCM of 760,910,935,670,405 with Prime Factorization
| 2 | 760, 910, 935, 670, 405 |
| 5 | 380, 455, 935, 335, 405 |
| 76, 91, 187, 67, 81 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 76 x 91 x 187 x 67 x 81 = 70186956840
Therefore, the lowest common multiple of 760,910,935,670,405 is 70186956840.
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.
760 x 910 x 935 x 670 x 405 = 175467392100000
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.
760 : 1, 2, 4, 5, 8, 10, 19, 20, 38, 40, 76, 95, 152, 190, 380, 760
910 : 1, 2, 5, 7, 10, 13, 14, 26, 35, 65, 70, 91, 130, 182, 455, 910
935 : 1, 5, 11, 17, 55, 85, 187, 935
670 : 1, 2, 5, 10, 67, 134, 335, 670
405 : 1, 3, 5, 9, 15, 27, 45, 81, 135, 405
5 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 760,910,935,670,405, is 5.
Now, the common factors can be found like this.
760:2x 2x 2x 5x 19
910:2x 5x 7x 13
935:5x 11x 17
670:2x 5x 67
405:3x 3x 3x 3x 5
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 5x 5x 5 = 500
Therefore, the value for common factors is 500.
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 = 175467392100000/(5x500)
LCM = 175467392100000/2500
LCM = 70186956840
Thus, we can understand that the LCM of 760,910,935,670,405 is 70186956840.
