Given numbers are 720,381,735,226,830
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 720,381,735,226,830 is 42023172240.
Find LCM of 720,381,735,226,830 with Prime Factorization
| 2 | 720, 381, 735, 226, 830 |
| 3 | 360, 381, 735, 113, 415 |
| 5 | 120, 127, 245, 113, 415 |
| 24, 127, 49, 113, 83 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 24 x 127 x 49 x 113 x 83 = 42023172240
Therefore, the lowest common multiple of 720,381,735,226,830 is 42023172240.
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.
720 x 381 x 735 x 226 x 830 = 37820855016000
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.
720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720
381 : 1, 3, 127, 381
735 : 1, 3, 5, 7, 15, 21, 35, 49, 105, 147, 245, 735
226 : 1, 2, 113, 226
830 : 1, 2, 5, 10, 83, 166, 415, 830
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 720,381,735,226,830, is 1.
Now, the common factors can be found like this.
720:2x 2x 2x 2x 3x 3x 5
381:3x 127
735:3x 5x 7x 7
226:2x 113
830:2x 5x 83
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 5x 5 = 900
Therefore, the value for common factors is 900.
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 = 37820855016000/(1x900)
LCM = 37820855016000/900
LCM = 42023172240
Thus, we can understand that the LCM of 720,381,735,226,830 is 42023172240.
