Given numbers are 472,649,860,257
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 472,649,860,257 is 286883960.
Find LCM of 472,649,860,257 with Prime Factorization
| 2 | 472, 649, 860, 257 |
| 2 | 236, 649, 430, 257 |
| 59 | 118, 649, 215, 257 |
| 2, 11, 215, 257 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 59 x 2 x 11 x 215 x 257 = 286883960
Therefore, the lowest common multiple of 472,649,860,257 is 286883960.
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.
472 x 649 x 860 x 257 = 67704614560
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.
472 : 1, 2, 4, 8, 59, 118, 236, 472
649 : 1, 11, 59, 649
860 : 1, 2, 4, 5, 10, 20, 43, 86, 172, 215, 430, 860
257 : 1, 257
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 472,649,860,257, is 1.
Now, the common factors can be found like this.
472:2x 2x 2x 59
649:11x 59
860:2x 2x 5x 43
257:257
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 59 = 236
Therefore, the value for common factors is 236.
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 = 67704614560/(1x236)
LCM = 67704614560/236
LCM = 286883960
Thus, we can understand that the LCM of 472,649,860,257 is 286883960.
