The LCM of 724,675,396,756 is 37629900.
Find LCM of 724,675,396,756 with Prime Factorization
| 2 | 724, 675, 396, 756 |
| 2 | 362, 675, 198, 378 |
| 3 | 181, 675, 99, 189 |
| 3 | 181, 225, 33, 63 |
| 3 | 181, 75, 11, 21 |
| 181, 25, 11, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 3 x 181 x 25 x 11 x 7 = 37629900
Therefore, the lowest common multiple of 724,675,396,756 is 37629900.
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.
724 x 675 x 396 x 756 = 146305051200
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.
724 : 1, 2, 4, 181, 362, 724
675 : 1, 3, 5, 9, 15, 25, 27, 45, 75, 135, 225, 675
396 : 1, 2, 3, 4, 6, 9, 11, 12, 18, 22, 33, 36, 44, 66, 99, 132, 198, 396
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
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 724,675,396,756, is 1.
Now, the common factors can be found like this.
724:2x 2x 181
675:3x 3x 3x 5x 5
396:2x 2x 3x 3x 11
756:2x 2x 3x 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 3x 3 = 3888
Therefore, the value for common factors is 3888.
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 = 146305051200/(1x3888)
LCM = 146305051200/3888
LCM = 37629900
Thus, we can understand that the LCM of 724,675,396,756 is 37629900.
