Given numbers are 563,966,540,942
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 563,966,540,942 is 7684713540.
Find LCM of 563,966,540,942 with Prime Factorization
| 2 | 563, 966, 540, 942 |
| 3 | 563, 483, 270, 471 |
| 563, 161, 90, 157 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 563 x 161 x 90 x 157 = 7684713540
Therefore, the lowest common multiple of 563,966,540,942 is 7684713540.
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.
563 x 966 x 540 x 942 = 276649687440
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.
563 : 1, 563
966 : 1, 2, 3, 6, 7, 14, 21, 23, 42, 46, 69, 138, 161, 322, 483, 966
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
942 : 1, 2, 3, 6, 157, 314, 471, 942
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 563,966,540,942, is 1.
Now, the common factors can be found like this.
563:563
966:2x 3x 7x 23
540:2x 2x 3x 3x 3x 5
942:2x 3x 157
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 3 = 36
Therefore, the value for common factors is 36.
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 = 276649687440/(1x36)
LCM = 276649687440/36
LCM = 7684713540
Thus, we can understand that the LCM of 563,966,540,942 is 7684713540.
