Given numbers are 978,755,631,510,723
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 978,755,631,510,723 is 1908890996730.
Find LCM of 978,755,631,510,723 with Prime Factorization
| 2 | 978, 755, 631, 510, 723 |
| 3 | 489, 755, 631, 255, 723 |
| 5 | 163, 755, 631, 85, 241 |
| 163, 151, 631, 17, 241 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 163 x 151 x 631 x 17 x 241 = 1908890996730
Therefore, the lowest common multiple of 978,755,631,510,723 is 1908890996730.
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 755 x 631 x 510 x 723 = 171800189705700
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
755 : 1, 5, 151, 755
631 : 1, 631
510 : 1, 2, 3, 5, 6, 10, 15, 17, 30, 34, 51, 85, 102, 170, 255, 510
723 : 1, 3, 241, 723
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 978,755,631,510,723, is 1.
Now, the common factors can be found like this.
978:2x 3x 163
755:5x 151
631:631
510:2x 3x 5x 17
723:3x 241
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 5 = 90
Therefore, the value for common factors is 90.
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 = 171800189705700/(1x90)
LCM = 171800189705700/90
LCM = 1908890996730
Thus, we can understand that the LCM of 978,755,631,510,723 is 1908890996730.
