Find LCM of 360,836,990,456,431 with Prime Factorization
| 2 | 360, 836, 990, 456, 431 |
| 2 | 180, 418, 495, 228, 431 |
| 2 | 90, 209, 495, 114, 431 |
| 3 | 45, 209, 495, 57, 431 |
| 3 | 15, 209, 165, 19, 431 |
| 5 | 5, 209, 55, 19, 431 |
| 11 | 1, 209, 11, 19, 431 |
| 19 | 1, 19, 1, 19, 431 |
| 1, 1, 1, 1, 431 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 3 x 5 x 11 x 19 x 1 x 1 x 1 x 1 x 431 = 32428440
Therefore, the lowest common multiple of 360,836,990,456,431 is 32428440.
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.
360 x 836 x 990 x 456 x 431 = 58557979814400
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.
360 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 18, 20, 24, 30, 36, 40, 45, 60, 72, 90, 120, 180, 360
836 : 1, 2, 4, 11, 19, 22, 38, 44, 76, 209, 418, 836
990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990
456 : 1, 2, 3, 4, 6, 8, 12, 19, 24, 38, 57, 76, 114, 152, 228, 456
431 : 1, 431
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 360,836,990,456,431, is 1.
Now, the common factors can be found like this.
360:2x 2x 2x 3x 3x 5
836:2x 2x 11x 19
990:2x 3x 3x 5x 11
456:2x 2x 2x 3x 19
431:431
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 3x 3x 3x 5x 11x 19 = 1805760
Therefore, the value for common factors is 1805760.
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 = 58557979814400/(1x1805760)
LCM = 58557979814400/1805760
LCM = 32428440
Thus, we can understand that the LCM of 360,836,990,456,431 is 32428440.
