Given numbers are 786,195,156,417
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 786,195,156,417 is 14203020.
Find LCM of 786,195,156,417 with Prime Factorization
| 2 | 786, 195, 156, 417 |
| 3 | 393, 195, 78, 417 |
| 13 | 131, 65, 26, 139 |
| 131, 5, 2, 139 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 13 x 131 x 5 x 2 x 139 = 14203020
Therefore, the lowest common multiple of 786,195,156,417 is 14203020.
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.
786 x 195 x 156 x 417 = 9970520040
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.
786 : 1, 2, 3, 6, 131, 262, 393, 786
195 : 1, 3, 5, 13, 15, 39, 65, 195
156 : 1, 2, 3, 4, 6, 12, 13, 26, 39, 52, 78, 156
417 : 1, 3, 139, 417
3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 786,195,156,417, is 3.
Now, the common factors can be found like this.
786:2x 3x 131
195:3x 5x 13
156:2x 2x 3x 13
417:3x 139
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 13 = 234
Therefore, the value for common factors is 234.
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 = 9970520040/(3x234)
LCM = 9970520040/702
LCM = 14203020
Thus, we can understand that the LCM of 786,195,156,417 is 14203020.
