Given numbers are 261,551,143,372
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 261,551,143,372 is 87932988.
Find LCM of 261,551,143,372 with Prime Factorization
| 3 | 261, 551, 143, 372 |
| 29 | 87, 551, 143, 124 |
| 3, 19, 143, 124 |
Multiply the prime numbers at the bottom and the left side.
3 x 29 x 3 x 19 x 143 x 124 = 87932988
Therefore, the lowest common multiple of 261,551,143,372 is 87932988.
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.
261 x 551 x 143 x 372 = 7650169956
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.
261 : 1, 3, 9, 29, 87, 261
551 : 1, 19, 29, 551
143 : 1, 11, 13, 143
372 : 1, 2, 3, 4, 6, 12, 31, 62, 93, 124, 186, 372
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 261,551,143,372, is 1.
Now, the common factors can be found like this.
261:3x 3x 29
551:19x 29
143:11x 13
372:2x 2x 3x 31
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 29 = 87
Therefore, the value for common factors is 87.
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 = 7650169956/(1x87)
LCM = 7650169956/87
LCM = 87932988
Thus, we can understand that the LCM of 261,551,143,372 is 87932988.
