Given numbers are 661,141,768,548,417
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 661,141,768,548,417 is 454355620608.
Find LCM of 661,141,768,548,417 with Prime Factorization
| 2 | 661, 141, 768, 548, 417 |
| 2 | 661, 141, 384, 274, 417 |
| 3 | 661, 141, 192, 137, 417 |
| 661, 47, 64, 137, 139 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 661 x 47 x 64 x 137 x 139 = 454355620608
Therefore, the lowest common multiple of 661,141,768,548,417 is 454355620608.
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.
661 x 141 x 768 x 548 x 417 = 16356802341888
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.
661 : 1, 661
141 : 1, 3, 47, 141
768 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 128, 192, 256, 384, 768
548 : 1, 2, 4, 137, 274, 548
417 : 1, 3, 139, 417
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 661,141,768,548,417, is 1.
Now, the common factors can be found like this.
661:661
141:3x 47
768:2x 2x 2x 2x 2x 2x 2x 2x 3
548:2x 2x 137
417:3x 139
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 3 = 36
Therefore, the value for common factors is 36.
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 = 16356802341888/(1x36)
LCM = 16356802341888/36
LCM = 454355620608
Thus, we can understand that the LCM of 661,141,768,548,417 is 454355620608.
