Given numbers are 268,978,902,779,647
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 268,978,902,779,647 is 726571028436.
Find LCM of 268,978,902,779,647 with Prime Factorization
| 2 | 268, 978, 902, 779, 647 |
| 41 | 134, 489, 451, 779, 647 |
| 134, 489, 11, 19, 647 |
Multiply the prime numbers at the bottom and the left side.
2 x 41 x 134 x 489 x 11 x 19 x 647 = 726571028436
Therefore, the lowest common multiple of 268,978,902,779,647 is 726571028436.
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.
268 x 978 x 902 x 779 x 647 = 119157648663504
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.
268 : 1, 2, 4, 67, 134, 268
978 : 1, 2, 3, 6, 163, 326, 489, 978
902 : 1, 2, 11, 22, 41, 82, 451, 902
779 : 1, 19, 41, 779
647 : 1, 647
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 268,978,902,779,647, is 1.
Now, the common factors can be found like this.
268:2x 2x 67
978:2x 3x 163
902:2x 11x 41
779:19x 41
647:647
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 41 = 164
Therefore, the value for common factors is 164.
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 = 119157648663504/(1x164)
LCM = 119157648663504/164
LCM = 726571028436
Thus, we can understand that the LCM of 268,978,902,779,647 is 726571028436.
