Given numbers are 249,567,561,494,644
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 249,567,561,494,644 is 199980448668.
Find LCM of 249,567,561,494,644 with Prime Factorization
| 2 | 249, 567, 561, 494, 644 |
| 3 | 249, 567, 561, 247, 322 |
| 7 | 83, 189, 187, 247, 322 |
| 83, 27, 187, 247, 46 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 83 x 27 x 187 x 247 x 46 = 199980448668
Therefore, the lowest common multiple of 249,567,561,494,644 is 199980448668.
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.
249 x 567 x 561 x 494 x 644 = 25197536532168
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.
249 : 1, 3, 83, 249
567 : 1, 3, 7, 9, 21, 27, 63, 81, 189, 567
561 : 1, 3, 11, 17, 33, 51, 187, 561
494 : 1, 2, 13, 19, 26, 38, 247, 494
644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 249,567,561,494,644, is 1.
Now, the common factors can be found like this.
249:3x 83
567:3x 3x 3x 3x 7
561:3x 11x 17
494:2x 13x 19
644:2x 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 3x 3x 7 = 126
Therefore, the value for common factors is 126.
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 = 25197536532168/(1x126)
LCM = 25197536532168/126
LCM = 199980448668
Thus, we can understand that the LCM of 249,567,561,494,644 is 199980448668.
