Given numbers are 475,689,742,832,905
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 475,689,742,832,905 is 26538075200.
Find LCM of 475,689,742,832,905 with Prime Factorization
| 2 | 475, 689, 742, 832, 905 |
| 5 | 475, 689, 371, 416, 905 |
| 13 | 95, 689, 371, 416, 181 |
| 53 | 95, 53, 371, 32, 181 |
| 95, 1, 7, 32, 181 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 13 x 53 x 95 x 1 x 7 x 32 x 181 = 26538075200
Therefore, the lowest common multiple of 475,689,742,832,905 is 26538075200.
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.
475 x 689 x 742 x 832 x 905 = 182847338128000
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.
475 : 1, 5, 19, 25, 95, 475
689 : 1, 13, 53, 689
742 : 1, 2, 7, 14, 53, 106, 371, 742
832 : 1, 2, 4, 8, 13, 16, 26, 32, 52, 64, 104, 208, 416, 832
905 : 1, 5, 181, 905
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 475,689,742,832,905, is 1.
Now, the common factors can be found like this.
475:5x 5x 19
689:13x 53
742:2x 7x 53
832:2x 2x 2x 2x 2x 2x 13
905:5x 181
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 13x 53 = 6890
Therefore, the value for common factors is 6890.
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 = 182847338128000/(1x6890)
LCM = 182847338128000/6890
LCM = 26538075200
Thus, we can understand that the LCM of 475,689,742,832,905 is 26538075200.
