Given numbers are 613,945,687,756
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 613,945,687,756 is 530625060.
Find LCM of 613,945,687,756 with Prime Factorization
| 3 | 613, 945, 687, 756 |
| 3 | 613, 315, 229, 252 |
| 3 | 613, 105, 229, 84 |
| 7 | 613, 35, 229, 28 |
| 613, 5, 229, 4 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 3 x 7 x 613 x 5 x 229 x 4 = 530625060
Therefore, the lowest common multiple of 613,945,687,756 is 530625060.
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.
613 x 945 x 687 x 756 = 300864409020
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.
613 : 1, 613
945 : 1, 3, 5, 7, 9, 15, 21, 27, 35, 45, 63, 105, 135, 189, 315, 945
687 : 1, 3, 229, 687
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 613,945,687,756, is 1.
Now, the common factors can be found like this.
613:613
945:3x 3x 3x 5x 7
687:3x 229
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.
3x 3x 3x 3x 7 = 567
Therefore, the value for common factors is 567.
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 = 300864409020/(1x567)
LCM = 300864409020/567
LCM = 530625060
Thus, we can understand that the LCM of 613,945,687,756 is 530625060.
