The LCM of 756,802,172,741 is 3219819876.
Find LCM of 756,802,172,741 with Prime Factorization
| 2 | 756, 802, 172, 741 |
| 2 | 378, 401, 86, 741 |
| 3 | 189, 401, 43, 741 |
| 63, 401, 43, 247 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 63 x 401 x 43 x 247 = 3219819876
Therefore, the lowest common multiple of 756,802,172,741 is 3219819876.
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.
756 x 802 x 172 x 741 = 77275677024
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.
756 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 27, 28, 36, 42, 54, 63, 84, 108, 126, 189, 252, 378, 756
802 : 1, 2, 401, 802
172 : 1, 2, 4, 43, 86, 172
741 : 1, 3, 13, 19, 39, 57, 247, 741
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 756,802,172,741, is 1.
Now, the common factors can be found like this.
756:2x 2x 3x 3x 3x 7
802:2x 401
172:2x 2x 43
741:3x 13x 19
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 3 = 24
Therefore, the value for common factors is 24.
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 = 77275677024/(1x24)
LCM = 77275677024/24
LCM = 3219819876
Thus, we can understand that the LCM of 756,802,172,741 is 3219819876.
