Given numbers are 399,171,577,440,915
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 399,171,577,440,915 is 18537555960.
Find LCM of 399,171,577,440,915 with Prime Factorization
| 3 | 399, 171, 577, 440, 915 |
| 5 | 133, 57, 577, 440, 305 |
| 19 | 133, 57, 577, 88, 61 |
| 7, 3, 577, 88, 61 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 19 x 7 x 3 x 577 x 88 x 61 = 18537555960
Therefore, the lowest common multiple of 399,171,577,440,915 is 18537555960.
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.
399 x 171 x 577 x 440 x 915 = 15849610345800
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.
399 : 1, 3, 7, 19, 21, 57, 133, 399
171 : 1, 3, 9, 19, 57, 171
577 : 1, 577
440 : 1, 2, 4, 5, 8, 10, 11, 20, 22, 40, 44, 55, 88, 110, 220, 440
915 : 1, 3, 5, 15, 61, 183, 305, 915
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 399,171,577,440,915, is 1.
Now, the common factors can be found like this.
399:3x 7x 19
171:3x 3x 19
577:577
440:2x 2x 2x 5x 11
915:3x 5x 61
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 5x 19 = 855
Therefore, the value for common factors is 855.
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 = 15849610345800/(1x855)
LCM = 15849610345800/855
LCM = 18537555960
Thus, we can understand that the LCM of 399,171,577,440,915 is 18537555960.
