Given numbers are 452,396,720,386
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 452,396,720,386 is 172727280.
Find LCM of 452,396,720,386 with Prime Factorization
| 2 | 452, 396, 720, 386 |
| 2 | 226, 198, 360, 193 |
| 3 | 113, 99, 180, 193 |
| 3 | 113, 33, 60, 193 |
| 113, 11, 20, 193 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 113 x 11 x 20 x 193 = 172727280
Therefore, the lowest common multiple of 452,396,720,386 is 172727280.
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.
452 x 396 x 720 x 386 = 49745456640
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.
452 : 1, 2, 4, 113, 226, 452
396 : 1, 2, 3, 4, 6, 9, 11, 12, 18, 22, 33, 36, 44, 66, 99, 132, 198, 396
720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720
386 : 1, 2, 193, 386
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 452,396,720,386, is 2.
Now, the common factors can be found like this.
452:2x 2x 113
396:2x 2x 3x 3x 11
720:2x 2x 2x 2x 3x 3x 5
386:2x 193
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 2x 2x 3x 3 = 144
Therefore, the value for common factors is 144.
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 = 49745456640/(2x144)
LCM = 49745456640/288
LCM = 172727280
Thus, we can understand that the LCM of 452,396,720,386 is 172727280.
