Given numbers are 978,551,437,626,546
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 978,551,437,626,546 is 353023827702.
Find LCM of 978,551,437,626,546 with Prime Factorization
| 2 | 978, 551, 437, 626, 546 |
| 3 | 489, 551, 437, 313, 273 |
| 19 | 163, 551, 437, 313, 91 |
| 163, 29, 23, 313, 91 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 19 x 163 x 29 x 23 x 313 x 91 = 353023827702
Therefore, the lowest common multiple of 978,551,437,626,546 is 353023827702.
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.
978 x 551 x 437 x 626 x 546 = 80489432716056
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.
978 : 1, 2, 3, 6, 163, 326, 489, 978
551 : 1, 19, 29, 551
437 : 1, 19, 23, 437
626 : 1, 2, 313, 626
546 : 1, 2, 3, 6, 7, 13, 14, 21, 26, 39, 42, 78, 91, 182, 273, 546
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 978,551,437,626,546, is 1.
Now, the common factors can be found like this.
978:2x 3x 163
551:19x 29
437:19x 23
626:2x 313
546:2x 3x 7x 13
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 3x 19 = 228
Therefore, the value for common factors is 228.
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 = 80489432716056/(1x228)
LCM = 80489432716056/228
LCM = 353023827702
Thus, we can understand that the LCM of 978,551,437,626,546 is 353023827702.
