Given numbers are 760,454,908,838
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 760,454,908,838 is 72285880.
Find LCM of 760,454,908,838 with Prime Factorization
| 2 | 760, 454, 908, 838 |
| 2 | 380, 227, 454, 419 |
| 227 | 190, 227, 227, 419 |
| 190, 1, 1, 419 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 227 x 190 x 1 x 1 x 419 = 72285880
Therefore, the lowest common multiple of 760,454,908,838 is 72285880.
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.
760 x 454 x 908 x 838 = 262542316160
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.
760 : 1, 2, 4, 5, 8, 10, 19, 20, 38, 40, 76, 95, 152, 190, 380, 760
454 : 1, 2, 227, 454
908 : 1, 2, 4, 227, 454, 908
838 : 1, 2, 419, 838
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 760,454,908,838, is 2.
Now, the common factors can be found like this.
760:2x 2x 2x 5x 19
454:2x 227
908:2x 2x 227
838:2x 419
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 227 = 1816
Therefore, the value for common factors is 1816.
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 = 262542316160/(2x1816)
LCM = 262542316160/3632
LCM = 72285880
Thus, we can understand that the LCM of 760,454,908,838 is 72285880.
