Given numbers are 640,281,899,846,282
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 640,281,899,846,282 is 68389015680.
Find LCM of 640,281,899,846,282 with Prime Factorization
| 2 | 640, 281, 899, 846, 282 |
| 3 | 320, 281, 899, 423, 141 |
| 47 | 320, 281, 899, 47, 141 |
| 320, 281, 899, 1, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 47 x 320 x 281 x 899 x 1 x 3 = 68389015680
Therefore, the lowest common multiple of 640,281,899,846,282 is 68389015680.
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.
640 x 281 x 899 x 846 x 282 = 38571404843520
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.
640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640
281 : 1, 281
899 : 1, 29, 31, 899
846 : 1, 2, 3, 6, 9, 18, 47, 94, 141, 282, 423, 846
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 640,281,899,846,282, is 1.
Now, the common factors can be found like this.
640:2x 2x 2x 2x 2x 2x 2x 5
281:281
899:29x 31
846:2x 3x 3x 47
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 3x 47 = 564
Therefore, the value for common factors is 564.
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 = 38571404843520/(1x564)
LCM = 38571404843520/564
LCM = 68389015680
Thus, we can understand that the LCM of 640,281,899,846,282 is 68389015680.
