Given numbers are 910,704,686,174,642
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 910,704,686,174,642 is 146111085120.
Find LCM of 910,704,686,174,642 with Prime Factorization
| 2 | 910, 704, 686, 174, 642 |
| 3 | 455, 352, 343, 87, 321 |
| 7 | 455, 352, 343, 29, 107 |
| 65, 352, 49, 29, 107 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 65 x 352 x 49 x 29 x 107 = 146111085120
Therefore, the lowest common multiple of 910,704,686,174,642 is 146111085120.
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.
910 x 704 x 686 x 174 x 642 = 49093324600320
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.
910 : 1, 2, 5, 7, 10, 13, 14, 26, 35, 65, 70, 91, 130, 182, 455, 910
704 : 1, 2, 4, 8, 11, 16, 22, 32, 44, 64, 88, 176, 352, 704
686 : 1, 2, 7, 14, 49, 98, 343, 686
174 : 1, 2, 3, 6, 29, 58, 87, 174
642 : 1, 2, 3, 6, 107, 214, 321, 642
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 910,704,686,174,642, is 2.
Now, the common factors can be found like this.
910:2x 5x 7x 13
704:2x 2x 2x 2x 2x 2x 11
686:2x 7x 7x 7
174:2x 3x 29
642:2x 3x 107
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 3x 7 = 168
Therefore, the value for common factors is 168.
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 = 49093324600320/(2x168)
LCM = 49093324600320/336
LCM = 146111085120
Thus, we can understand that the LCM of 910,704,686,174,642 is 146111085120.
