Given numbers are 913,722,247,529,978
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 913,722,247,529,978 is 2216745617658.
Find LCM of 913,722,247,529,978 with Prime Factorization
| 2 | 913, 722, 247, 529, 978 |
| 19 | 913, 361, 247, 529, 489 |
| 913, 19, 13, 529, 489 |
Multiply the prime numbers at the bottom and the left side.
2 x 19 x 913 x 19 x 13 x 529 x 489 = 2216745617658
Therefore, the lowest common multiple of 913,722,247,529,978 is 2216745617658.
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.
913 x 722 x 247 x 529 x 978 = 84236333471004
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.
913 : 1, 11, 83, 913
722 : 1, 2, 19, 38, 361, 722
247 : 1, 13, 19, 247
529 : 1, 23, 529
978 : 1, 2, 3, 6, 163, 326, 489, 978
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 913,722,247,529,978, is 1.
Now, the common factors can be found like this.
913:11x 83
722:2x 19x 19
247:13x 19
529:23x 23
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 19 = 38
Therefore, the value for common factors is 38.
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 = 84236333471004/(1x38)
LCM = 84236333471004/38
LCM = 2216745617658
Thus, we can understand that the LCM of 913,722,247,529,978 is 2216745617658.
