The LCM of 963,578,721,756 is 2407912164.
Find LCM of 963,578,721,756 with Prime Factorization
| 2 | 963, 578, 721, 756 |
| 3 | 963, 289, 721, 378 |
| 3 | 321, 289, 721, 126 |
| 7 | 107, 289, 721, 42 |
| 107, 289, 103, 6 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 7 x 107 x 289 x 103 x 6 = 2407912164
Therefore, the lowest common multiple of 963,578,721,756 is 2407912164.
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.
963 x 578 x 721 x 756 = 303396932664
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.
963 : 1, 3, 9, 107, 321, 963
578 : 1, 2, 17, 34, 289, 578
721 : 1, 7, 103, 721
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 963,578,721,756, is 1.
Now, the common factors can be found like this.
963:3x 3x 107
578:2x 17x 17
721:7x 103
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 3x 3x 7 = 126
Therefore, the value for common factors is 126.
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 = 303396932664/(1x126)
LCM = 303396932664/126
LCM = 2407912164
Thus, we can understand that the LCM of 963,578,721,756 is 2407912164.
