Find LCM of 138,465,485,210,429 with Prime Factorization
2 | 138, 465, 485, 210, 429 |
3 | 69, 465, 485, 105, 429 |
5 | 23, 155, 485, 35, 143 |
23, 31, 97, 7, 143 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 23 x 31 x 97 x 7 x 143 = 2076904830
Therefore, the lowest common multiple of 138,465,485,210,429 is 2076904830.
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.
138 x 465 x 485 x 210 x 429 = 2803821520500
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.
138 : 1, 2, 3, 6, 23, 46, 69, 138
465 : 1, 3, 5, 15, 31, 93, 155, 465
485 : 1, 5, 97, 485
210 : 1, 2, 3, 5, 6, 7, 10, 14, 15, 21, 30, 35, 42, 70, 105, 210
429 : 1, 3, 11, 13, 33, 39, 143, 429
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 138,465,485,210,429, is 1.
Now, the common factors can be found like this.
138:2x 3x 23
465:3x 5x 31
485:5x 97
210:2x 3x 5x 7
429:3x 11x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 3x 5x 5 = 1350
Therefore, the value for common factors is 1350.
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 = 2803821520500/(1x1350)
LCM = 2803821520500/1350
LCM = 2076904830
Thus, we can understand that the LCM of 138,465,485,210,429 is 2076904830.
