Given numbers are 756,822,131,247
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 756,822,131,247 is 3351279204.
Find LCM of 756,822,131,247 with Prime Factorization
| 2 | 756, 822, 131, 247 |
| 3 | 378, 411, 131, 247 |
| 126, 137, 131, 247 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 126 x 137 x 131 x 247 = 3351279204
Therefore, the lowest common multiple of 756,822,131,247 is 3351279204.
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 822 x 131 x 247 = 20107675224
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
822 : 1, 2, 3, 6, 137, 274, 411, 822
131 : 1, 131
247 : 1, 13, 19, 247
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 756,822,131,247, is 1.
Now, the common factors can be found like this.
756:2x 2x 3x 3x 3x 7
822:2x 3x 137
131:131
247:13x 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 3 = 6
Therefore, the value for common factors is 6.
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 = 20107675224/(1x6)
LCM = 20107675224/6
LCM = 3351279204
Thus, we can understand that the LCM of 756,822,131,247 is 3351279204.
