Given numbers are 427,546,242,247
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 427,546,242,247 is 76570494.
Find LCM of 427,546,242,247 with Prime Factorization
2 | 427, 546, 242, 247 |
7 | 427, 273, 121, 247 |
13 | 61, 39, 121, 247 |
61, 3, 121, 19 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 13 x 61 x 3 x 121 x 19 = 76570494
Therefore, the lowest common multiple of 427,546,242,247 is 76570494.
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.
427 x 546 x 242 x 247 = 13935829908
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.
427 : 1, 7, 61, 427
546 : 1, 2, 3, 6, 7, 13, 14, 21, 26, 39, 42, 78, 91, 182, 273, 546
242 : 1, 2, 11, 22, 121, 242
247 : 1, 13, 19, 247
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 427,546,242,247, is 1.
Now, the common factors can be found like this.
427:7x 61
546:2x 3x 7x 13
242:2x 11x 11
247:13x 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 7x 13 = 182
Therefore, the value for common factors is 182.
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 = 13935829908/(1x182)
LCM = 13935829908/182
LCM = 76570494
Thus, we can understand that the LCM of 427,546,242,247 is 76570494.
