Given numbers are 130,154,785,775
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 130,154,785,775 is 243593350.
Find LCM of 130,154,785,775 with Prime Factorization
| 2 | 130, 154, 785, 775 |
| 5 | 65, 77, 785, 775 |
| 13, 77, 157, 155 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 13 x 77 x 157 x 155 = 243593350
Therefore, the lowest common multiple of 130,154,785,775 is 243593350.
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.
130 x 154 x 785 x 775 = 12179667500
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.
130 : 1, 2, 5, 10, 13, 26, 65, 130
154 : 1, 2, 7, 11, 14, 22, 77, 154
785 : 1, 5, 157, 785
775 : 1, 5, 25, 31, 155, 775
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 130,154,785,775, is 1.
Now, the common factors can be found like this.
130:2x 5x 13
154:2x 7x 11
785:5x 157
775:5x 5x 31
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 5 = 50
Therefore, the value for common factors is 50.
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 = 12179667500/(1x50)
LCM = 12179667500/50
LCM = 243593350
Thus, we can understand that the LCM of 130,154,785,775 is 243593350.
