Given numbers are 759,129,540,640
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 759,129,540,640 is 187989120.
Find LCM of 759,129,540,640 with Prime Factorization
| 2 | 759, 129, 540, 640 |
| 2 | 759, 129, 270, 320 |
| 3 | 759, 129, 135, 160 |
| 5 | 253, 43, 45, 160 |
| 253, 43, 9, 32 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 253 x 43 x 9 x 32 = 187989120
Therefore, the lowest common multiple of 759,129,540,640 is 187989120.
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.
759 x 129 x 540 x 640 = 33838041600
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.
759 : 1, 3, 11, 23, 33, 69, 253, 759
129 : 1, 3, 43, 129
540 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 27, 30, 36, 45, 54, 60, 90, 108, 135, 180, 270, 540
640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 759,129,540,640, is 1.
Now, the common factors can be found like this.
759:3x 11x 23
129:3x 43
540:2x 2x 3x 3x 3x 5
640:2x 2x 2x 2x 2x 2x 2x 5
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 3x 3x 5 = 180
Therefore, the value for common factors is 180.
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 = 33838041600/(1x180)
LCM = 33838041600/180
LCM = 187989120
Thus, we can understand that the LCM of 759,129,540,640 is 187989120.
