Given numbers are 176,686,884,756
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 176,686,884,756 is 360215856.
Find LCM of 176,686,884,756 with Prime Factorization
| 2 | 176, 686, 884, 756 |
| 2 | 88, 343, 442, 378 |
| 7 | 44, 343, 221, 189 |
| 44, 49, 221, 27 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 44 x 49 x 221 x 27 = 360215856
Therefore, the lowest common multiple of 176,686,884,756 is 360215856.
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.
176 x 686 x 884 x 756 = 80688351744
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.
176 : 1, 2, 4, 8, 11, 16, 22, 44, 88, 176
686 : 1, 2, 7, 14, 49, 98, 343, 686
884 : 1, 2, 4, 13, 17, 26, 34, 52, 68, 221, 442, 884
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
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 176,686,884,756, is 2.
Now, the common factors can be found like this.
176:2x 2x 2x 2x 11
686:2x 7x 7x 7
884:2x 2x 13x 17
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 7 = 112
Therefore, the value for common factors is 112.
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 = 80688351744/(2x112)
LCM = 80688351744/224
LCM = 360215856
Thus, we can understand that the LCM of 176,686,884,756 is 360215856.
