The LCM of 461,272,442,308,356 is 11171047888.
Find LCM of 461,272,442,308,356 with Prime Factorization
| 2 | 461, 272, 442, 308, 356 |
| 2 | 461, 136, 221, 154, 178 |
| 17 | 461, 68, 221, 77, 89 |
| 461, 4, 13, 77, 89 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 17 x 461 x 4 x 13 x 77 x 89 = 11171047888
Therefore, the lowest common multiple of 461,272,442,308,356 is 11171047888.
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.
461 x 272 x 442 x 308 x 356 = 6077050051072
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.
461 : 1, 461
272 : 1, 2, 4, 8, 16, 17, 34, 68, 136, 272
442 : 1, 2, 13, 17, 26, 34, 221, 442
308 : 1, 2, 4, 7, 11, 14, 22, 28, 44, 77, 154, 308
356 : 1, 2, 4, 89, 178, 356
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 461,272,442,308,356, is 1.
Now, the common factors can be found like this.
461:461
272:2x 2x 2x 2x 17
442:2x 13x 17
308:2x 2x 7x 11
356:2x 2x 89
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 2x 17 = 544
Therefore, the value for common factors is 544.
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 = 6077050051072/(1x544)
LCM = 6077050051072/544
LCM = 11171047888
Thus, we can understand that the LCM of 461,272,442,308,356 is 11171047888.
