Given numbers are 658,978,507,936,806
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 658,978,507,936,806 is 20228533416.
Find LCM of 658,978,507,936,806 with Prime Factorization
| 2 | 658, 978, 507, 936, 806 |
| 3 | 329, 489, 507, 468, 403 |
| 13 | 329, 163, 169, 156, 403 |
| 329, 163, 13, 12, 31 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 13 x 329 x 163 x 13 x 12 x 31 = 20228533416
Therefore, the lowest common multiple of 658,978,507,936,806 is 20228533416.
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.
658 x 978 x 507 x 936 x 806 = 246140794605888
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.
658 : 1, 2, 7, 14, 47, 94, 329, 658
978 : 1, 2, 3, 6, 163, 326, 489, 978
507 : 1, 3, 13, 39, 169, 507
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
806 : 1, 2, 13, 26, 31, 62, 403, 806
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 658,978,507,936,806, is 1.
Now, the common factors can be found like this.
658:2x 7x 47
978:2x 3x 163
507:3x 13x 13
936:2x 2x 2x 3x 3x 13
806:2x 13x 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 2x 2x 3x 3x 13x 13 = 12168
Therefore, the value for common factors is 12168.
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 = 246140794605888/(1x12168)
LCM = 246140794605888/12168
LCM = 20228533416
Thus, we can understand that the LCM of 658,978,507,936,806 is 20228533416.
