Given numbers are 843,648,637,245
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 843,648,637,245 is 579950280.
Find LCM of 843,648,637,245 with Prime Factorization
| 3 | 843, 648, 637, 245 |
| 7 | 281, 216, 637, 245 |
| 7 | 281, 216, 91, 35 |
| 281, 216, 13, 5 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 7 x 281 x 216 x 13 x 5 = 579950280
Therefore, the lowest common multiple of 843,648,637,245 is 579950280.
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.
843 x 648 x 637 x 245 = 85252691160
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.
843 : 1, 3, 281, 843
648 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 81, 108, 162, 216, 324, 648
637 : 1, 7, 13, 49, 91, 637
245 : 1, 5, 7, 35, 49, 245
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 843,648,637,245, is 1.
Now, the common factors can be found like this.
843:3x 281
648:2x 2x 2x 3x 3x 3x 3
637:7x 7x 13
245:5x 7x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 7x 7 = 147
Therefore, the value for common factors is 147.
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 = 85252691160/(1x147)
LCM = 85252691160/147
LCM = 579950280
Thus, we can understand that the LCM of 843,648,637,245 is 579950280.
