Given numbers are 150,505,138,780,102
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 150,505,138,780,102 is 154014900.
Find LCM of 150,505,138,780,102 with Prime Factorization
| 2 | 150, 505, 138, 780, 102 |
| 3 | 75, 505, 69, 390, 51 |
| 5 | 25, 505, 23, 130, 17 |
| 5, 101, 23, 26, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 5 x 101 x 23 x 26 x 17 = 154014900
Therefore, the lowest common multiple of 150,505,138,780,102 is 154014900.
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.
150 x 505 x 138 x 780 x 102 = 831680460000
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.
150 : 1, 2, 3, 5, 6, 10, 15, 25, 30, 50, 75, 150
505 : 1, 5, 101, 505
138 : 1, 2, 3, 6, 23, 46, 69, 138
780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780
102 : 1, 2, 3, 6, 17, 34, 51, 102
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 150,505,138,780,102, is 1.
Now, the common factors can be found like this.
150:2x 3x 5x 5
505:5x 101
138:2x 3x 23
780:2x 2x 3x 5x 13
102:2x 3x 17
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 3x 5x 5 = 5400
Therefore, the value for common factors is 5400.
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 = 831680460000/(1x5400)
LCM = 831680460000/5400
LCM = 154014900
Thus, we can understand that the LCM of 150,505,138,780,102 is 154014900.
