Given numbers are 203,578,194,154,322
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 203,578,194,154,322 is 2879493694.
Find LCM of 203,578,194,154,322 with Prime Factorization
| 2 | 203, 578, 194, 154, 322 |
| 7 | 203, 289, 97, 77, 161 |
| 29, 289, 97, 11, 23 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 29 x 289 x 97 x 11 x 23 = 2879493694
Therefore, the lowest common multiple of 203,578,194,154,322 is 2879493694.
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.
203 x 578 x 194 x 154 x 322 = 1128761528048
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.
203 : 1, 7, 29, 203
578 : 1, 2, 17, 34, 289, 578
194 : 1, 2, 97, 194
154 : 1, 2, 7, 11, 14, 22, 77, 154
322 : 1, 2, 7, 14, 23, 46, 161, 322
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 203,578,194,154,322, is 1.
Now, the common factors can be found like this.
203:7x 29
578:2x 17x 17
194:2x 97
154:2x 7x 11
322:2x 7x 23
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 7x 7 = 392
Therefore, the value for common factors is 392.
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 = 1128761528048/(1x392)
LCM = 1128761528048/392
LCM = 2879493694
Thus, we can understand that the LCM of 203,578,194,154,322 is 2879493694.
