Given numbers are 138,533,702,285
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 138,533,702,285 is 62888670.
Find LCM of 138,533,702,285 with Prime Factorization
2 | 138, 533, 702, 285 |
3 | 69, 533, 351, 285 |
13 | 23, 533, 117, 95 |
23, 41, 9, 95 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 13 x 23 x 41 x 9 x 95 = 62888670
Therefore, the lowest common multiple of 138,533,702,285 is 62888670.
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 533 x 702 x 285 = 14715948780
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
533 : 1, 13, 41, 533
702 : 1, 2, 3, 6, 9, 13, 18, 26, 27, 39, 54, 78, 117, 234, 351, 702
285 : 1, 3, 5, 15, 19, 57, 95, 285
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 138,533,702,285, is 1.
Now, the common factors can be found like this.
138:2x 3x 23
533:13x 41
702:2x 3x 3x 3x 13
285:3x 5x 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 3x 3x 13 = 234
Therefore, the value for common factors is 234.
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 = 14715948780/(1x234)
LCM = 14715948780/234
LCM = 62888670
Thus, we can understand that the LCM of 138,533,702,285 is 62888670.
