Given numbers are 650,746,448,985,169
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 650,746,448,985,169 is 139084836800.
Find LCM of 650,746,448,985,169 with Prime Factorization
| 2 | 650, 746, 448, 985, 169 |
| 5 | 325, 373, 224, 985, 169 |
| 13 | 65, 373, 224, 197, 169 |
| 5, 373, 224, 197, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 13 x 5 x 373 x 224 x 197 x 13 = 139084836800
Therefore, the lowest common multiple of 650,746,448,985,169 is 139084836800.
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.
650 x 746 x 448 x 985 x 169 = 36162057568000
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.
650 : 1, 2, 5, 10, 13, 25, 26, 50, 65, 130, 325, 650
746 : 1, 2, 373, 746
448 : 1, 2, 4, 7, 8, 14, 16, 28, 32, 56, 64, 112, 224, 448
985 : 1, 5, 197, 985
169 : 1, 13, 169
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 650,746,448,985,169, is 1.
Now, the common factors can be found like this.
650:2x 5x 5x 13
746:2x 373
448:2x 2x 2x 2x 2x 2x 7
985:5x 197
169:13x 13
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 13 = 260
Therefore, the value for common factors is 260.
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 = 36162057568000/(1x260)
LCM = 36162057568000/260
LCM = 139084836800
Thus, we can understand that the LCM of 650,746,448,985,169 is 139084836800.
