Given numbers are 228,722,209,322
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 228,722,209,322 is 7671972.
Find LCM of 228,722,209,322 with Prime Factorization
| 2 | 228, 722, 209, 322 |
| 19 | 114, 361, 209, 161 |
| 6, 19, 11, 161 |
Multiply the prime numbers at the bottom and the left side.
2 x 19 x 6 x 19 x 11 x 161 = 7671972
Therefore, the lowest common multiple of 228,722,209,322 is 7671972.
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.
228 x 722 x 209 x 322 = 11078327568
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.
228 : 1, 2, 3, 4, 6, 12, 19, 38, 57, 76, 114, 228
722 : 1, 2, 19, 38, 361, 722
209 : 1, 11, 19, 209
322 : 1, 2, 7, 14, 23, 46, 161, 322
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 228,722,209,322, is 1.
Now, the common factors can be found like this.
228:2x 2x 3x 19
722:2x 19x 19
209:11x 19
322:2x 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 2x 19x 19 = 1444
Therefore, the value for common factors is 1444.
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 = 11078327568/(1x1444)
LCM = 11078327568/1444
LCM = 7671972
Thus, we can understand that the LCM of 228,722,209,322 is 7671972.
