Find LCM of 138,562,429,874,770 with Prime Factorization
| 2 | 138, 562, 429, 874, 770 |
| 3 | 69, 281, 429, 437, 385 |
| 11 | 23, 281, 143, 437, 385 |
| 23 | 23, 281, 13, 437, 35 |
| 1, 281, 13, 19, 35 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 23 x 1 x 281 x 13 x 19 x 35 = 3687593910
Therefore, the lowest common multiple of 138,562,429,874,770 is 3687593910.
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 562 x 429 x 874 x 770 = 22391070221520
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
562 : 1, 2, 281, 562
429 : 1, 3, 11, 13, 33, 39, 143, 429
874 : 1, 2, 19, 23, 38, 46, 437, 874
770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 138,562,429,874,770, is 1.
Now, the common factors can be found like this.
138:2x 3x 23
562:2x 281
429:3x 11x 13
874:2x 19x 23
770:2x 5x 7x 11
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 11x 23 = 6072
Therefore, the value for common factors is 6072.
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 = 22391070221520/(1x6072)
LCM = 22391070221520/6072
LCM = 3687593910
Thus, we can understand that the LCM of 138,562,429,874,770 is 3687593910.
