Given numbers are 649,243,224,385,755
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 649,243,224,385,755 is 26671407840.
Find LCM of 649,243,224,385,755 with Prime Factorization
| 5 | 649, 243, 224, 385, 755 |
| 7 | 649, 243, 224, 77, 151 |
| 11 | 649, 243, 32, 11, 151 |
| 59, 243, 32, 1, 151 |
Multiply the prime numbers at the bottom and the left side.
5 x 7 x 11 x 59 x 243 x 32 x 1 x 151 = 26671407840
Therefore, the lowest common multiple of 649,243,224,385,755 is 26671407840.
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.
649 x 243 x 224 x 385 x 755 = 10268492018400
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.
649 : 1, 11, 59, 649
243 : 1, 3, 9, 27, 81, 243
224 : 1, 2, 4, 7, 8, 14, 16, 28, 32, 56, 112, 224
385 : 1, 5, 7, 11, 35, 55, 77, 385
755 : 1, 5, 151, 755
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 649,243,224,385,755, is 1.
Now, the common factors can be found like this.
649:11x 59
243:3x 3x 3x 3x 3
224:2x 2x 2x 2x 2x 7
385:5x 7x 11
755:5x 151
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 7x 11 = 385
Therefore, the value for common factors is 385.
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 = 10268492018400/(1x385)
LCM = 10268492018400/385
LCM = 26671407840
Thus, we can understand that the LCM of 649,243,224,385,755 is 26671407840.
