Given numbers are 139,297,611,705,221
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 139,297,611,705,221 is 2144032605.
Find LCM of 139,297,611,705,221 with Prime Factorization
| 3 | 139, 297, 611, 705, 221 |
| 13 | 139, 99, 611, 235, 221 |
| 47 | 139, 99, 47, 235, 17 |
| 139, 99, 1, 5, 17 |
Multiply the prime numbers at the bottom and the left side.
3 x 13 x 47 x 139 x 99 x 1 x 5 x 17 = 2144032605
Therefore, the lowest common multiple of 139,297,611,705,221 is 2144032605.
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.
139 x 297 x 611 x 705 x 221 = 3930011764965
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.
139 : 1, 139
297 : 1, 3, 9, 11, 27, 33, 99, 297
611 : 1, 13, 47, 611
705 : 1, 3, 5, 15, 47, 141, 235, 705
221 : 1, 13, 17, 221
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 139,297,611,705,221, is 1.
Now, the common factors can be found like this.
139:139
297:3x 3x 3x 11
611:13x 47
705:3x 5x 47
221:13x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 13x 47 = 1833
Therefore, the value for common factors is 1833.
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 = 3930011764965/(1x1833)
LCM = 3930011764965/1833
LCM = 2144032605
Thus, we can understand that the LCM of 139,297,611,705,221 is 2144032605.
