Given numbers are 637,843,991,203,249
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 637,843,991,203,249 is 1280904500967.
Find LCM of 637,843,991,203,249 with Prime Factorization
| 3 | 637, 843, 991, 203, 249 |
| 7 | 637, 281, 991, 203, 83 |
| 91, 281, 991, 29, 83 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 91 x 281 x 991 x 29 x 83 = 1280904500967
Therefore, the lowest common multiple of 637,843,991,203,249 is 1280904500967.
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.
637 x 843 x 991 x 203 x 249 = 26898994520307
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.
637 : 1, 7, 13, 49, 91, 637
843 : 1, 3, 281, 843
991 : 1, 991
203 : 1, 7, 29, 203
249 : 1, 3, 83, 249
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 637,843,991,203,249, is 1.
Now, the common factors can be found like this.
637:7x 7x 13
843:3x 281
991:991
203:7x 29
249:3x 83
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 7 = 21
Therefore, the value for common factors is 21.
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 = 26898994520307/(1x21)
LCM = 26898994520307/21
LCM = 1280904500967
Thus, we can understand that the LCM of 637,843,991,203,249 is 1280904500967.
