Given numbers are 641,860,293,172,282
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 641,860,293,172,282 is 22774204380.
Find LCM of 641,860,293,172,282 with Prime Factorization
| 2 | 641, 860, 293, 172, 282 |
| 2 | 641, 430, 293, 86, 141 |
| 43 | 641, 215, 293, 43, 141 |
| 641, 5, 293, 1, 141 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 43 x 641 x 5 x 293 x 1 x 141 = 22774204380
Therefore, the lowest common multiple of 641,860,293,172,282 is 22774204380.
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.
641 x 860 x 293 x 172 x 282 = 7834326306720
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.
641 : 1, 641
860 : 1, 2, 4, 5, 10, 20, 43, 86, 172, 215, 430, 860
293 : 1, 293
172 : 1, 2, 4, 43, 86, 172
282 : 1, 2, 3, 6, 47, 94, 141, 282
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 641,860,293,172,282, is 1.
Now, the common factors can be found like this.
641:641
860:2x 2x 5x 43
293:293
172:2x 2x 43
282:2x 3x 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 2x 43 = 344
Therefore, the value for common factors is 344.
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 = 7834326306720/(1x344)
LCM = 7834326306720/344
LCM = 22774204380
Thus, we can understand that the LCM of 641,860,293,172,282 is 22774204380.
