Given numbers are 342,303,642,665,788
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 342,303,642,665,788 is 50967757260.
Find LCM of 342,303,642,665,788 with Prime Factorization
| 2 | 342, 303, 642, 665, 788 |
| 3 | 171, 303, 321, 665, 394 |
| 19 | 57, 101, 107, 665, 394 |
| 3, 101, 107, 35, 394 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 19 x 3 x 101 x 107 x 35 x 394 = 50967757260
Therefore, the lowest common multiple of 342,303,642,665,788 is 50967757260.
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.
342 x 303 x 642 x 665 x 788 = 34861945965840
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.
342 : 1, 2, 3, 6, 9, 18, 19, 38, 57, 114, 171, 342
303 : 1, 3, 101, 303
642 : 1, 2, 3, 6, 107, 214, 321, 642
665 : 1, 5, 7, 19, 35, 95, 133, 665
788 : 1, 2, 4, 197, 394, 788
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 342,303,642,665,788, is 1.
Now, the common factors can be found like this.
342:2x 3x 3x 19
303:3x 101
642:2x 3x 107
665:5x 7x 19
788:2x 2x 197
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 3x 3x 19 = 684
Therefore, the value for common factors is 684.
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 = 34861945965840/(1x684)
LCM = 34861945965840/684
LCM = 50967757260
Thus, we can understand that the LCM of 342,303,642,665,788 is 50967757260.
