Given numbers are 789,429,351,438
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 789,429,351,438 is 148254678.
Find LCM of 789,429,351,438 with Prime Factorization
3 | 789, 429, 351, 438 |
13 | 263, 143, 117, 146 |
263, 11, 9, 146 |
Multiply the prime numbers at the bottom and the left side.
3 x 13 x 263 x 11 x 9 x 146 = 148254678
Therefore, the lowest common multiple of 789,429,351,438 is 148254678.
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.
789 x 429 x 351 x 438 = 52037391978
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.
789 : 1, 3, 263, 789
429 : 1, 3, 11, 13, 33, 39, 143, 429
351 : 1, 3, 9, 13, 27, 39, 117, 351
438 : 1, 2, 3, 6, 73, 146, 219, 438
3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 789,429,351,438, is 3.
Now, the common factors can be found like this.
789:3x 263
429:3x 11x 13
351:3x 3x 3x 13
438:2x 3x 73
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 13 = 117
Therefore, the value for common factors is 117.
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 = 52037391978/(3x117)
LCM = 52037391978/351
LCM = 148254678
Thus, we can understand that the LCM of 789,429,351,438 is 148254678.
