Find LCM of 624,787,351,168 with Prime Factorization
| 2 | 624, 787, 351, 168 |
| 2 | 312, 787, 351, 84 |
| 2 | 156, 787, 351, 42 |
| 3 | 78, 787, 351, 21 |
| 13 | 26, 787, 117, 7 |
| 2, 787, 9, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 13 x 2 x 787 x 9 x 7 = 30938544
Therefore, the lowest common multiple of 624,787,351,168 is 30938544.
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.
624 x 787 x 351 x 168 = 28958477184
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.
624 : 1, 2, 3, 4, 6, 8, 12, 13, 16, 24, 26, 39, 48, 52, 78, 104, 156, 208, 312, 624
787 : 1, 787
351 : 1, 3, 9, 13, 27, 39, 117, 351
168 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 21, 24, 28, 42, 56, 84, 168
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 624,787,351,168, is 1.
Now, the common factors can be found like this.
624:2x 2x 2x 2x 3x 13
787:787
351:3x 3x 3x 13
168:2x 2x 2x 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 3x 3x 13 = 936
Therefore, the value for common factors is 936.
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 = 28958477184/(1x936)
LCM = 28958477184/936
LCM = 30938544
Thus, we can understand that the LCM of 624,787,351,168 is 30938544.
