2 | 36, 905, 54, 869 |
3 | 18, 905, 27, 869 |
3 | 6, 905, 9, 869 |
2, 905, 3, 869 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 3 x 2 x 905 x 3 x 869 = 679488480
Therefore, the lowest common multiple of 288,905,432,869 is 679488480.
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.
288 x 905 x 432 x 869 = 97846341120
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.
288 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 32, 36, 48, 72, 96, 144, 288
905 : 1, 5, 181, 905
432 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 36, 48, 54, 72, 108, 144, 216, 432
869 : 1, 11, 79, 869
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 288,905,432,869, is 1.
Now, the common factors can be found like this.
288:2x 2x 2x 2x 2x 3x 3
905:5x 181
432:2x 2x 2x 2x 3x 3x 3
869:11x 79
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 = 97846341120/(1x144)
LCM = 97846341120/144
LCM = 679488480
Thus, we can understand that the LCM of 288,905,432,869 is 679488480.
