Given numbers are 605,502,649,930
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 605,502,649,930 is 1666456770.
Find LCM of 605,502,649,930 with Prime Factorization
| 2 | 605, 502, 649, 930 |
| 5 | 605, 251, 649, 465 |
| 11 | 121, 251, 649, 93 |
| 11, 251, 59, 93 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 11 x 11 x 251 x 59 x 93 = 1666456770
Therefore, the lowest common multiple of 605,502,649,930 is 1666456770.
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 502 x 649 x 930 = 183310244700
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
502 : 1, 2, 251, 502
649 : 1, 11, 59, 649
930 : 1, 2, 3, 5, 6, 10, 15, 30, 31, 62, 93, 155, 186, 310, 465, 930
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 605,502,649,930, is 1.
Now, the common factors can be found like this.
605:5x 11x 11
502:2x 251
649:11x 59
930:2x 3x 5x 31
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 11 = 110
Therefore, the value for common factors is 110.
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 = 183310244700/(1x110)
LCM = 183310244700/110
LCM = 1666456770
Thus, we can understand that the LCM of 605,502,649,930 is 1666456770.
