Given numbers are 278,364,504,554,978
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 278,364,504,554,978 is 41120279928.
Find LCM of 278,364,504,554,978 with Prime Factorization
| 2 | 278, 364, 504, 554, 978 |
| 2 | 139, 182, 252, 277, 489 |
| 3 | 139, 91, 126, 277, 489 |
| 7 | 139, 91, 42, 277, 163 |
| 139, 13, 6, 277, 163 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 139 x 13 x 6 x 277 x 163 = 41120279928
Therefore, the lowest common multiple of 278,364,504,554,978 is 41120279928.
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.
278 x 364 x 504 x 554 x 978 = 27632828111616
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.
278 : 1, 2, 139, 278
364 : 1, 2, 4, 7, 13, 14, 26, 28, 52, 91, 182, 364
504 : 1, 2, 3, 4, 6, 7, 8, 9, 12, 14, 18, 21, 24, 28, 36, 42, 56, 63, 72, 84, 126, 168, 252, 504
554 : 1, 2, 277, 554
978 : 1, 2, 3, 6, 163, 326, 489, 978
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 278,364,504,554,978, is 2.
Now, the common factors can be found like this.
278:2x 139
364:2x 2x 7x 13
504:2x 2x 2x 3x 3x 7
554:2x 277
978:2x 3x 163
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 2x 3x 7 = 336
Therefore, the value for common factors is 336.
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 = 27632828111616/(2x336)
LCM = 27632828111616/672
LCM = 41120279928
Thus, we can understand that the LCM of 278,364,504,554,978 is 41120279928.
