Given numbers are 763,405,600,161
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 763,405,600,161 is 284293800.
Find LCM of 763,405,600,161 with Prime Factorization
| 3 | 763, 405, 600, 161 |
| 5 | 763, 135, 200, 161 |
| 7 | 763, 27, 40, 161 |
| 109, 27, 40, 23 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 7 x 109 x 27 x 40 x 23 = 284293800
Therefore, the lowest common multiple of 763,405,600,161 is 284293800.
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.
763 x 405 x 600 x 161 = 29850849000
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.
763 : 1, 7, 109, 763
405 : 1, 3, 5, 9, 15, 27, 45, 81, 135, 405
600 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 25, 30, 40, 50, 60, 75, 100, 120, 150, 200, 300, 600
161 : 1, 7, 23, 161
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 763,405,600,161, is 1.
Now, the common factors can be found like this.
763:7x 109
405:3x 3x 3x 3x 5
600:2x 2x 2x 3x 5x 5
161:7x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5x 7 = 105
Therefore, the value for common factors is 105.
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 = 29850849000/(1x105)
LCM = 29850849000/105
LCM = 284293800
Thus, we can understand that the LCM of 763,405,600,161 is 284293800.
