Given numbers are 969,121,520,950
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 969,121,520,950 is 304847400.
Find LCM of 969,121,520,950 with Prime Factorization
| 2 | 969, 121, 520, 950 |
| 5 | 969, 121, 260, 475 |
| 19 | 969, 121, 52, 95 |
| 51, 121, 52, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 19 x 51 x 121 x 52 x 5 = 304847400
Therefore, the lowest common multiple of 969,121,520,950 is 304847400.
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.
969 x 121 x 520 x 950 = 57921006000
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.
969 : 1, 3, 17, 19, 51, 57, 323, 969
121 : 1, 11, 121
520 : 1, 2, 4, 5, 8, 10, 13, 20, 26, 40, 52, 65, 104, 130, 260, 520
950 : 1, 2, 5, 10, 19, 25, 38, 50, 95, 190, 475, 950
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 969,121,520,950, is 1.
Now, the common factors can be found like this.
969:3x 17x 19
121:11x 11
520:2x 2x 2x 5x 13
950:2x 5x 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 5x 19 = 190
Therefore, the value for common factors is 190.
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 = 57921006000/(1x190)
LCM = 57921006000/190
LCM = 304847400
Thus, we can understand that the LCM of 969,121,520,950 is 304847400.
