The LCM of 450,638,308,865,438 is 25380501300.
Find LCM of 450,638,308,865,438 with Prime Factorization
| 2 | 450, 638, 308, 865, 438 |
| 3 | 225, 319, 154, 865, 219 |
| 5 | 75, 319, 154, 865, 73 |
| 11 | 15, 319, 154, 173, 73 |
| 15, 29, 14, 173, 73 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 11 x 15 x 29 x 14 x 173 x 73 = 25380501300
Therefore, the lowest common multiple of 450,638,308,865,438 is 25380501300.
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.
450 x 638 x 308 x 865 x 438 = 33502261716000
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.
450 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 25, 30, 45, 50, 75, 90, 150, 225, 450
638 : 1, 2, 11, 22, 29, 58, 319, 638
308 : 1, 2, 4, 7, 11, 14, 22, 28, 44, 77, 154, 308
865 : 1, 5, 173, 865
438 : 1, 2, 3, 6, 73, 146, 219, 438
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 450,638,308,865,438, is 1.
Now, the common factors can be found like this.
450:2x 3x 3x 5x 5
638:2x 11x 29
308:2x 2x 7x 11
865:5x 173
438:2x 3x 73
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 3x 5x 11 = 1320
Therefore, the value for common factors is 1320.
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 = 33502261716000/(1x1320)
LCM = 33502261716000/1320
LCM = 25380501300
Thus, we can understand that the LCM of 450,638,308,865,438 is 25380501300.
