Given numbers are 220,723,936,855
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 220,723,936,855 is 235726920.
Find LCM of 220,723,936,855 with Prime Factorization
| 2 | 220, 723, 936, 855 |
| 2 | 110, 723, 468, 855 |
| 3 | 55, 723, 234, 855 |
| 3 | 55, 241, 78, 285 |
| 5 | 55, 241, 26, 95 |
| 11, 241, 26, 19 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 5 x 11 x 241 x 26 x 19 = 235726920
Therefore, the lowest common multiple of 220,723,936,855 is 235726920.
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.
220 x 723 x 936 x 855 = 127292536800
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.
220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220
723 : 1, 3, 241, 723
936 : 1, 2, 3, 4, 6, 8, 9, 12, 13, 18, 24, 26, 36, 39, 52, 72, 78, 104, 117, 156, 234, 312, 468, 936
855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 220,723,936,855, is 1.
Now, the common factors can be found like this.
220:2x 2x 5x 11
723:3x 241
936:2x 2x 2x 3x 3x 13
855:3x 3x 5x 19
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 3x 3x 5 = 540
Therefore, the value for common factors is 540.
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 = 127292536800/(1x540)
LCM = 127292536800/540
LCM = 235726920
Thus, we can understand that the LCM of 220,723,936,855 is 235726920.
