Given numbers are 551,721,967,203
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 551,721,967,203 is 384161057.
Find LCM of 551,721,967,203 with Prime Factorization
| 7 | 551, 721, 967, 203 |
| 29 | 551, 103, 967, 29 |
| 19, 103, 967, 1 |
Multiply the prime numbers at the bottom and the left side.
7 x 29 x 19 x 103 x 967 x 1 = 384161057
Therefore, the lowest common multiple of 551,721,967,203 is 384161057.
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.
551 x 721 x 967 x 203 = 77984694571
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.
551 : 1, 19, 29, 551
721 : 1, 7, 103, 721
967 : 1, 967
203 : 1, 7, 29, 203
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 551,721,967,203, is 1.
Now, the common factors can be found like this.
551:19x 29
721:7x 103
967:967
203:7x 29
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
7x 29 = 203
Therefore, the value for common factors is 203.
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 = 77984694571/(1x203)
LCM = 77984694571/203
LCM = 384161057
Thus, we can understand that the LCM of 551,721,967,203 is 384161057.
