Given numbers are 605,550,994,961,388
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 605,550,994,961,388 is 560579072900.
Find LCM of 605,550,994,961,388 with Prime Factorization
| 2 | 605, 550, 994, 961, 388 |
| 5 | 605, 275, 497, 961, 194 |
| 11 | 121, 55, 497, 961, 194 |
| 11, 5, 497, 961, 194 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 11 x 11 x 5 x 497 x 961 x 194 = 560579072900
Therefore, the lowest common multiple of 605,550,994,961,388 is 560579072900.
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.
605 x 550 x 994 x 961 x 388 = 123327396038000
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.
605 : 1, 5, 11, 55, 121, 605
550 : 1, 2, 5, 10, 11, 22, 25, 50, 55, 110, 275, 550
994 : 1, 2, 7, 14, 71, 142, 497, 994
961 : 1, 31, 961
388 : 1, 2, 4, 97, 194, 388
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 605,550,994,961,388, is 1.
Now, the common factors can be found like this.
605:5x 11x 11
550:2x 5x 5x 11
994:2x 7x 71
961:31x 31
388:2x 2x 97
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 5x 11 = 220
Therefore, the value for common factors is 220.
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 = 123327396038000/(1x220)
LCM = 123327396038000/220
LCM = 560579072900
Thus, we can understand that the LCM of 605,550,994,961,388 is 560579072900.
