Given numbers are 540,458,561,152
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 540,458,561,152 is 878727960.
Find LCM of 540,458,561,152 with Prime Factorization
| 2 | 540, 458, 561, 152 |
| 2 | 270, 229, 561, 76 |
| 3 | 135, 229, 561, 38 |
| 45, 229, 187, 38 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 45 x 229 x 187 x 38 = 878727960
Therefore, the lowest common multiple of 540,458,561,152 is 878727960.
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.
540 x 458 x 561 x 152 = 21089471040
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.
540 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 27, 30, 36, 45, 54, 60, 90, 108, 135, 180, 270, 540
458 : 1, 2, 229, 458
561 : 1, 3, 11, 17, 33, 51, 187, 561
152 : 1, 2, 4, 8, 19, 38, 76, 152
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 540,458,561,152, is 1.
Now, the common factors can be found like this.
540:2x 2x 3x 3x 3x 5
458:2x 229
561:3x 11x 17
152:2x 2x 2x 19
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 = 21089471040/(1x24)
LCM = 21089471040/24
LCM = 878727960
Thus, we can understand that the LCM of 540,458,561,152 is 878727960.
