Find LCM of 921,193,280,855,589 with Prime Factorization
| 3 | 921, 193, 280, 855, 589 |
| 5 | 307, 193, 280, 285, 589 |
| 19 | 307, 193, 56, 57, 589 |
| 307, 193, 56, 3, 31 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 19 x 307 x 193 x 56 x 3 x 31 = 87945074280
Therefore, the lowest common multiple of 921,193,280,855,589 is 87945074280.
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.
921 x 193 x 280 x 855 x 589 = 25064346169800
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.
921 : 1, 3, 307, 921
193 : 1, 193
280 : 1, 2, 4, 5, 7, 8, 10, 14, 20, 28, 35, 40, 56, 70, 140, 280
855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855
589 : 1, 19, 31, 589
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 921,193,280,855,589, is 1.
Now, the common factors can be found like this.
921:3x 307
193:193
280:2x 2x 2x 5x 7
855:3x 3x 5x 19
589:19x 31
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 19 = 285
Therefore, the value for common factors is 285.
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 = 25064346169800/(1x285)
LCM = 25064346169800/285
LCM = 87945074280
Thus, we can understand that the LCM of 921,193,280,855,589 is 87945074280.
