Given numbers are 249,149,438,644,186
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 249,149,438,644,186 is 54069958572.
Find LCM of 249,149,438,644,186 with Prime Factorization
| 2 | 249, 149, 438, 644, 186 |
| 3 | 249, 149, 219, 322, 93 |
| 83, 149, 73, 322, 31 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 83 x 149 x 73 x 322 x 31 = 54069958572
Therefore, the lowest common multiple of 249,149,438,644,186 is 54069958572.
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 149 x 438 x 644 x 186 = 1946518508592
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
149 : 1, 149
438 : 1, 2, 3, 6, 73, 146, 219, 438
644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644
186 : 1, 2, 3, 6, 31, 62, 93, 186
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 249,149,438,644,186, is 1.
Now, the common factors can be found like this.
249:3x 83
149:149
438:2x 3x 73
644:2x 2x 7x 23
186:2x 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.
2x 2x 3x 3 = 36
Therefore, the value for common factors is 36.
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 = 1946518508592/(1x36)
LCM = 1946518508592/36
LCM = 54069958572
Thus, we can understand that the LCM of 249,149,438,644,186 is 54069958572.
