The LCM of 820,260,956,611 is 119743780.
Find LCM of 820,260,956,611 with Prime Factorization
| 2 | 820, 260, 956, 611 |
| 2 | 410, 130, 478, 611 |
| 5 | 205, 65, 239, 611 |
| 13 | 41, 13, 239, 611 |
| 41, 1, 239, 47 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 13 x 41 x 1 x 239 x 47 = 119743780
Therefore, the lowest common multiple of 820,260,956,611 is 119743780.
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.
820 x 260 x 956 x 611 = 124533531200
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.
820 : 1, 2, 4, 5, 10, 20, 41, 82, 164, 205, 410, 820
260 : 1, 2, 4, 5, 10, 13, 20, 26, 52, 65, 130, 260
956 : 1, 2, 4, 239, 478, 956
611 : 1, 13, 47, 611
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 820,260,956,611, is 1.
Now, the common factors can be found like this.
820:2x 2x 5x 41
260:2x 2x 5x 13
956:2x 2x 239
611:13x 47
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 2x 5x 13 = 1040
Therefore, the value for common factors is 1040.
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 = 124533531200/(1x1040)
LCM = 124533531200/1040
LCM = 119743780
Thus, we can understand that the LCM of 820,260,956,611 is 119743780.
