Given numbers are 417,154,187,689
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 417,154,187,689 is 752185434.
Find LCM of 417,154,187,689 with Prime Factorization
| 11 | 417, 154, 187, 689 |
| 417, 14, 17, 689 |
Multiply the prime numbers at the bottom and the left side.
11 x 417 x 14 x 17 x 689 = 752185434
Therefore, the lowest common multiple of 417,154,187,689 is 752185434.
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.
417 x 154 x 187 x 689 = 8274039774
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.
417 : 1, 3, 139, 417
154 : 1, 2, 7, 11, 14, 22, 77, 154
187 : 1, 11, 17, 187
689 : 1, 13, 53, 689
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 417,154,187,689, is 1.
Now, the common factors can be found like this.
417:3x 139
154:2x 7x 11
187:11x 17
689:13x 53
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
11 = 11
Therefore, the value for common factors is 11.
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 = 8274039774/(1x11)
LCM = 8274039774/11
LCM = 752185434
Thus, we can understand that the LCM of 417,154,187,689 is 752185434.
