The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 987,290,153,420,232 is 58390920.
Find LCM of 987,290,153,420,232 with Prime Factorization
| 2 | 987, 290, 153, 420, 232 |
| 2 | 987, 145, 153, 210, 116 |
| 3 | 987, 145, 153, 105, 58 |
| 5 | 329, 145, 51, 35, 58 |
| 7 | 329, 29, 51, 7, 58 |
| 29 | 47, 29, 51, 1, 58 |
| 47, 1, 51, 1, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 7 x 29 x 47 x 1 x 51 x 1 x 2 = 58390920
Therefore, the lowest common multiple of 987,290,153,420,232 is 58390920.
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.
987 x 290 x 153 x 420 x 232 = 4267208433600
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.
987 : 1, 3, 7, 21, 47, 141, 329, 987
290 : 1, 2, 5, 10, 29, 58, 145, 290
153 : 1, 3, 9, 17, 51, 153
420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420
232 : 1, 2, 4, 8, 29, 58, 116, 232
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 987,290,153,420,232, is 1.
Now, the common factors can be found like this.
987:3x 7x 47
290:2x 5x 29
153:3x 3x 17
420:2x 2x 3x 5x 7
232:2x 2x 2x 29
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 3x 3x 5x 7x 29 = 73080
Therefore, the value for common factors is 73080.
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 = 4267208433600/(1x73080)
LCM = 4267208433600/73080
LCM = 58390920
Thus, we can understand that the LCM of 987,290,153,420,232 is 58390920.
