Given numbers are 784,116,310,115,119
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 784,116,310,115,119 is 1377915280.
Find LCM of 784,116,310,115,119 with Prime Factorization
| 2 | 784, 116, 310, 115, 119 |
| 2 | 392, 58, 155, 115, 119 |
| 5 | 196, 29, 155, 115, 119 |
| 7 | 196, 29, 31, 23, 119 |
| 28, 29, 31, 23, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 7 x 28 x 29 x 31 x 23 x 17 = 1377915280
Therefore, the lowest common multiple of 784,116,310,115,119 is 1377915280.
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.
784 x 116 x 310 x 115 x 119 = 385816278400
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.
784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784
116 : 1, 2, 4, 29, 58, 116
310 : 1, 2, 5, 10, 31, 62, 155, 310
115 : 1, 5, 23, 115
119 : 1, 7, 17, 119
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 784,116,310,115,119, is 1.
Now, the common factors can be found like this.
784:2x 2x 2x 2x 7x 7
116:2x 2x 29
310:2x 5x 31
115:5x 23
119:7x 17
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 5x 7 = 280
Therefore, the value for common factors is 280.
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 = 385816278400/(1x280)
LCM = 385816278400/280
LCM = 1377915280
Thus, we can understand that the LCM of 784,116,310,115,119 is 1377915280.
