The LCM of 270,421,235,945 is 37397430.
Find LCM of 270,421,235,945 with Prime Factorization
| 3 | 270, 421, 235, 945 |
| 3 | 90, 421, 235, 315 |
| 3 | 30, 421, 235, 105 |
| 5 | 10, 421, 235, 35 |
| 2, 421, 47, 7 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 3 x 5 x 2 x 421 x 47 x 7 = 37397430
Therefore, the lowest common multiple of 270,421,235,945 is 37397430.
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.
270 x 421 x 235 x 945 = 25243265250
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.
270 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 90, 135, 270
421 : 1, 421
235 : 1, 5, 47, 235
945 : 1, 3, 5, 7, 9, 15, 21, 27, 35, 45, 63, 105, 135, 189, 315, 945
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 270,421,235,945, is 1.
Now, the common factors can be found like this.
270:2x 3x 3x 3x 5
421:421
235:5x 47
945:3x 3x 3x 5x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 3x 5x 5 = 675
Therefore, the value for common factors is 675.
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 = 25243265250/(1x675)
LCM = 25243265250/675
LCM = 37397430
Thus, we can understand that the LCM of 270,421,235,945 is 37397430.
