Given numbers are 159,371,720,247,657
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 159,371,720,247,657 is 4816440720.
Find LCM of 159,371,720,247,657 with Prime Factorization
| 3 | 159, 371, 720, 247, 657 |
| 3 | 53, 371, 240, 247, 219 |
| 53 | 53, 371, 80, 247, 73 |
| 1, 7, 80, 247, 73 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 53 x 1 x 7 x 80 x 247 x 73 = 4816440720
Therefore, the lowest common multiple of 159,371,720,247,657 is 4816440720.
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.
159 x 371 x 720 x 247 x 657 = 6892326670320
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.
159 : 1, 3, 53, 159
371 : 1, 7, 53, 371
720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720
247 : 1, 13, 19, 247
657 : 1, 3, 9, 73, 219, 657
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 159,371,720,247,657, is 1.
Now, the common factors can be found like this.
159:3x 53
371:7x 53
720:2x 2x 2x 2x 3x 3x 5
247:13x 19
657:3x 3x 73
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 3x 53 = 1431
Therefore, the value for common factors is 1431.
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 = 6892326670320/(1x1431)
LCM = 6892326670320/1431
LCM = 4816440720
Thus, we can understand that the LCM of 159,371,720,247,657 is 4816440720.
