Given numbers are 723,942,518,644,517
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 723,942,518,644,517 is 1398350635836.
Find LCM of 723,942,518,644,517 with Prime Factorization
| 2 | 723, 942, 518, 644, 517 |
| 3 | 723, 471, 259, 322, 517 |
| 7 | 241, 157, 259, 322, 517 |
| 241, 157, 37, 46, 517 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 241 x 157 x 37 x 46 x 517 = 1398350635836
Therefore, the lowest common multiple of 723,942,518,644,517 is 1398350635836.
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.
723 x 942 x 518 x 644 x 517 = 117461453410224
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.
723 : 1, 3, 241, 723
942 : 1, 2, 3, 6, 157, 314, 471, 942
518 : 1, 2, 7, 14, 37, 74, 259, 518
644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644
517 : 1, 11, 47, 517
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 723,942,518,644,517, is 1.
Now, the common factors can be found like this.
723:3x 241
942:2x 3x 157
518:2x 7x 37
644:2x 2x 7x 23
517:11x 47
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 7 = 84
Therefore, the value for common factors is 84.
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 = 117461453410224/(1x84)
LCM = 117461453410224/84
LCM = 1398350635836
Thus, we can understand that the LCM of 723,942,518,644,517 is 1398350635836.
