Given numbers are 291,438,988,546,766
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 291,438,988,546,766 is 56269053204.
Find LCM of 291,438,988,546,766 with Prime Factorization
| 2 | 291, 438, 988, 546, 766 |
| 3 | 291, 219, 494, 273, 383 |
| 13 | 97, 73, 494, 91, 383 |
| 97, 73, 38, 7, 383 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 13 x 97 x 73 x 38 x 7 x 383 = 56269053204
Therefore, the lowest common multiple of 291,438,988,546,766 is 56269053204.
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.
291 x 438 x 988 x 546 x 766 = 52667833798944
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.
291 : 1, 3, 97, 291
438 : 1, 2, 3, 6, 73, 146, 219, 438
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
546 : 1, 2, 3, 6, 7, 13, 14, 21, 26, 39, 42, 78, 91, 182, 273, 546
766 : 1, 2, 383, 766
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 291,438,988,546,766, is 1.
Now, the common factors can be found like this.
291:3x 97
438:2x 3x 73
988:2x 2x 13x 19
546:2x 3x 7x 13
766:2x 383
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 13 = 936
Therefore, the value for common factors is 936.
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 = 52667833798944/(1x936)
LCM = 52667833798944/936
LCM = 56269053204
Thus, we can understand that the LCM of 291,438,988,546,766 is 56269053204.
