Find LCM of 904,702,821,143,744 with Prime Factorization
| 2 | 904, 702, 821, 143, 744 |
| 2 | 452, 351, 821, 143, 372 |
| 2 | 226, 351, 821, 143, 186 |
| 3 | 113, 351, 821, 143, 93 |
| 13 | 113, 117, 821, 143, 31 |
| 113, 9, 821, 11, 31 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 13 x 113 x 9 x 821 x 11 x 31 = 88832745144
Therefore, the lowest common multiple of 904,702,821,143,744 is 88832745144.
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.
904 x 702 x 821 x 143 x 744 = 55431632969856
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.
904 : 1, 2, 4, 8, 113, 226, 452, 904
702 : 1, 2, 3, 6, 9, 13, 18, 26, 27, 39, 54, 78, 117, 234, 351, 702
821 : 1, 821
143 : 1, 11, 13, 143
744 : 1, 2, 3, 4, 6, 8, 12, 24, 31, 62, 93, 124, 186, 248, 372, 744
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 904,702,821,143,744, is 1.
Now, the common factors can be found like this.
904:2x 2x 2x 113
702:2x 3x 3x 3x 13
821:821
143:11x 13
744:2x 2x 2x 3x 31
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 13 = 624
Therefore, the value for common factors is 624.
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 = 55431632969856/(1x624)
LCM = 55431632969856/624
LCM = 88832745144
Thus, we can understand that the LCM of 904,702,821,143,744 is 88832745144.
