Find LCM of 814,780,936,252 with Prime Factorization
| 2 | 814, 780, 936, 252 |
| 2 | 407, 390, 468, 126 |
| 3 | 407, 195, 234, 63 |
| 3 | 407, 65, 78, 21 |
| 13 | 407, 65, 26, 7 |
| 407, 5, 2, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 13 x 407 x 5 x 2 x 7 = 13333320
Therefore, the lowest common multiple of 814,780,936,252 is 13333320.
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.
814 x 780 x 936 x 252 = 149759850240
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.
814 : 1, 2, 11, 22, 37, 74, 407, 814
780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780
936 : 1, 2, 3, 4, 6, 8, 9, 12, 13, 18, 24, 26, 36, 39, 52, 72, 78, 104, 117, 156, 234, 312, 468, 936
252 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 28, 36, 42, 63, 84, 126, 252
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 814,780,936,252, is 2.
Now, the common factors can be found like this.
814:2x 11x 37
780:2x 2x 3x 5x 13
936:2x 2x 2x 3x 3x 13
252:2x 2x 3x 3x 7
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 3x 3x 13 = 5616
Therefore, the value for common factors is 5616.
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 = 149759850240/(2x5616)
LCM = 149759850240/11232
LCM = 13333320
Thus, we can understand that the LCM of 814,780,936,252 is 13333320.
