Given numbers are 123,409,786,126
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 123,409,786,126 is 276789114.
Find LCM of 123,409,786,126 with Prime Factorization
| 2 | 123, 409, 786, 126 |
| 3 | 123, 409, 393, 63 |
| 41, 409, 131, 21 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 41 x 409 x 131 x 21 = 276789114
Therefore, the lowest common multiple of 123,409,786,126 is 276789114.
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.
123 x 409 x 786 x 126 = 4982204052
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.
123 : 1, 3, 41, 123
409 : 1, 409
786 : 1, 2, 3, 6, 131, 262, 393, 786
126 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 42, 63, 126
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 123,409,786,126, is 1.
Now, the common factors can be found like this.
123:3x 41
409:409
786:2x 3x 131
126:2x 3x 3x 7
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 3 = 18
Therefore, the value for common factors is 18.
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 = 4982204052/(1x18)
LCM = 4982204052/18
LCM = 276789114
Thus, we can understand that the LCM of 123,409,786,126 is 276789114.
