Given numbers are 740,836,758,855
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 740,836,758,855 is 527545260.
Find LCM of 740,836,758,855 with Prime Factorization
| 2 | 740, 836, 758, 855 |
| 2 | 370, 418, 379, 855 |
| 5 | 185, 209, 379, 855 |
| 19 | 37, 209, 379, 171 |
| 37, 11, 379, 9 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 19 x 37 x 11 x 379 x 9 = 527545260
Therefore, the lowest common multiple of 740,836,758,855 is 527545260.
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.
740 x 836 x 758 x 855 = 400934397600
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.
740 : 1, 2, 4, 5, 10, 20, 37, 74, 148, 185, 370, 740
836 : 1, 2, 4, 11, 19, 22, 38, 44, 76, 209, 418, 836
758 : 1, 2, 379, 758
855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 740,836,758,855, is 1.
Now, the common factors can be found like this.
740:2x 2x 5x 37
836:2x 2x 11x 19
758:2x 379
855:3x 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 2x 2x 5x 19 = 760
Therefore, the value for common factors is 760.
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 = 400934397600/(1x760)
LCM = 400934397600/760
LCM = 527545260
Thus, we can understand that the LCM of 740,836,758,855 is 527545260.
