Given numbers are 292,308,328,646
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 292,308,328,646 is 595511224.
Find LCM of 292,308,328,646 with Prime Factorization
| 2 | 292, 308, 328, 646 |
| 2 | 146, 154, 164, 323 |
| 73, 77, 82, 323 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 73 x 77 x 82 x 323 = 595511224
Therefore, the lowest common multiple of 292,308,328,646 is 595511224.
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.
292 x 308 x 328 x 646 = 19056359168
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.
292 : 1, 2, 4, 73, 146, 292
308 : 1, 2, 4, 7, 11, 14, 22, 28, 44, 77, 154, 308
328 : 1, 2, 4, 8, 41, 82, 164, 328
646 : 1, 2, 17, 19, 34, 38, 323, 646
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 292,308,328,646, is 2.
Now, the common factors can be found like this.
292:2x 2x 73
308:2x 2x 7x 11
328:2x 2x 2x 41
646:2x 17x 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 2x 2x 2 = 16
Therefore, the value for common factors is 16.
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 = 19056359168/(2x16)
LCM = 19056359168/32
LCM = 595511224
Thus, we can understand that the LCM of 292,308,328,646 is 595511224.
