Given numbers are 281,126,152,204,641
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 281,126,152,204,641 is 29322257832.
Find LCM of 281,126,152,204,641 with Prime Factorization
| 2 | 281, 126, 152, 204, 641 |
| 2 | 281, 63, 76, 102, 641 |
| 3 | 281, 63, 38, 51, 641 |
| 281, 21, 38, 17, 641 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 281 x 21 x 38 x 17 x 641 = 29322257832
Therefore, the lowest common multiple of 281,126,152,204,641 is 29322257832.
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.
281 x 126 x 152 x 204 x 641 = 703734187968
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.
281 : 1, 281
126 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 42, 63, 126
152 : 1, 2, 4, 8, 19, 38, 76, 152
204 : 1, 2, 3, 4, 6, 12, 17, 34, 51, 68, 102, 204
641 : 1, 641
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 281,126,152,204,641, is 1.
Now, the common factors can be found like this.
281:281
126:2x 3x 3x 7
152:2x 2x 2x 19
204:2x 2x 3x 17
641:641
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 3 = 24
Therefore, the value for common factors is 24.
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 = 703734187968/(1x24)
LCM = 703734187968/24
LCM = 29322257832
Thus, we can understand that the LCM of 281,126,152,204,641 is 29322257832.
