Given numbers are 320,872,880,254
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 320,872,880,254 is 48727360.
Find LCM of 320,872,880,254 with Prime Factorization
| 2 | 320, 872, 880, 254 |
| 2 | 160, 436, 440, 127 |
| 2 | 80, 218, 220, 127 |
| 2 | 40, 109, 110, 127 |
| 5 | 20, 109, 55, 127 |
| 4, 109, 11, 127 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 5 x 4 x 109 x 11 x 127 = 48727360
Therefore, the lowest common multiple of 320,872,880,254 is 48727360.
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.
320 x 872 x 880 x 254 = 62371020800
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.
320 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 160, 320
872 : 1, 2, 4, 8, 109, 218, 436, 872
880 : 1, 2, 4, 5, 8, 10, 11, 16, 20, 22, 40, 44, 55, 80, 88, 110, 176, 220, 440, 880
254 : 1, 2, 127, 254
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 320,872,880,254, is 2.
Now, the common factors can be found like this.
320:2x 2x 2x 2x 2x 2x 5
872:2x 2x 2x 109
880:2x 2x 2x 2x 5x 11
254:2x 127
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 2x 2x 2x 5 = 640
Therefore, the value for common factors is 640.
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 = 62371020800/(2x640)
LCM = 62371020800/1280
LCM = 48727360
Thus, we can understand that the LCM of 320,872,880,254 is 48727360.
