Find LCM of 428,624,514,990,955 with Prime Factorization
| 2 | 428, 624, 514, 990, 955 |
| 2 | 214, 312, 257, 495, 955 |
| 3 | 107, 156, 257, 495, 955 |
| 5 | 107, 52, 257, 165, 955 |
| 107, 52, 257, 33, 191 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 107 x 52 x 257 x 33 x 191 = 540777734640
Therefore, the lowest common multiple of 428,624,514,990,955 is 540777734640.
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.
428 x 624 x 514 x 990 x 955 = 129786656313600
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.
428 : 1, 2, 4, 107, 214, 428
624 : 1, 2, 3, 4, 6, 8, 12, 13, 16, 24, 26, 39, 48, 52, 78, 104, 156, 208, 312, 624
514 : 1, 2, 257, 514
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
955 : 1, 5, 191, 955
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 428,624,514,990,955, is 1.
Now, the common factors can be found like this.
428:2x 2x 107
624:2x 2x 2x 2x 3x 13
514:2x 257
990:2x 3x 3x 5x 11
955:5x 191
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 5 = 240
Therefore, the value for common factors is 240.
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 = 129786656313600/(1x240)
LCM = 129786656313600/240
LCM = 540777734640
Thus, we can understand that the LCM of 428,624,514,990,955 is 540777734640.
