Find LCM of 811,744,624,869,170 with Prime Factorization
| 2 | 811, 744, 624, 869, 170 |
| 2 | 811, 372, 312, 869, 85 |
| 2 | 811, 186, 156, 869, 85 |
| 3 | 811, 93, 78, 869, 85 |
| 811, 31, 26, 869, 85 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 811 x 31 x 26 x 869 x 85 = 1158792938160
Therefore, the lowest common multiple of 811,744,624,869,170 is 1158792938160.
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.
811 x 744 x 624 x 869 x 170 = 55622061031680
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.
811 : 1, 811
744 : 1, 2, 3, 4, 6, 8, 12, 24, 31, 62, 93, 124, 186, 248, 372, 744
624 : 1, 2, 3, 4, 6, 8, 12, 13, 16, 24, 26, 39, 48, 52, 78, 104, 156, 208, 312, 624
869 : 1, 11, 79, 869
170 : 1, 2, 5, 10, 17, 34, 85, 170
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 811,744,624,869,170, is 1.
Now, the common factors can be found like this.
811:811
744:2x 2x 2x 3x 31
624:2x 2x 2x 2x 3x 13
869:11x 79
170:2x 5x 17
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 3 = 48
Therefore, the value for common factors is 48.
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 = 55622061031680/(1x48)
LCM = 55622061031680/48
LCM = 1158792938160
Thus, we can understand that the LCM of 811,744,624,869,170 is 1158792938160.
