Given numbers are 249,819,747,772
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 249,819,747,772 is 52478244.
Find LCM of 249,819,747,772 with Prime Factorization
| 3 | 249, 819, 747, 772 |
| 3 | 83, 273, 249, 772 |
| 83 | 83, 91, 83, 772 |
| 1, 91, 1, 772 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 83 x 1 x 91 x 1 x 772 = 52478244
Therefore, the lowest common multiple of 249,819,747,772 is 52478244.
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 819 x 747 x 772 = 117603744804
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
819 : 1, 3, 7, 9, 13, 21, 39, 63, 91, 117, 273, 819
747 : 1, 3, 9, 83, 249, 747
772 : 1, 2, 4, 193, 386, 772
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 249,819,747,772, is 1.
Now, the common factors can be found like this.
249:3x 83
819:3x 3x 7x 13
747:3x 3x 83
772:2x 2x 193
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 3x 83 = 2241
Therefore, the value for common factors is 2241.
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 = 117603744804/(1x2241)
LCM = 117603744804/2241
LCM = 52478244
Thus, we can understand that the LCM of 249,819,747,772 is 52478244.
