Given numbers are 305,716,870,718,812
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 305,716,870,718,812 is 47744637780.
Find LCM of 305,716,870,718,812 with Prime Factorization
| 2 | 305, 716, 870, 718, 812 |
| 2 | 305, 358, 435, 359, 406 |
| 5 | 305, 179, 435, 359, 203 |
| 29 | 61, 179, 87, 359, 203 |
| 61, 179, 3, 359, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 29 x 61 x 179 x 3 x 359 x 7 = 47744637780
Therefore, the lowest common multiple of 305,716,870,718,812 is 47744637780.
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.
305 x 716 x 870 x 718 x 812 = 110767559649600
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.
305 : 1, 5, 61, 305
716 : 1, 2, 4, 179, 358, 716
870 : 1, 2, 3, 5, 6, 10, 15, 29, 30, 58, 87, 145, 174, 290, 435, 870
718 : 1, 2, 359, 718
812 : 1, 2, 4, 7, 14, 28, 29, 58, 116, 203, 406, 812
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 305,716,870,718,812, is 1.
Now, the common factors can be found like this.
305:5x 61
716:2x 2x 179
870:2x 3x 5x 29
718:2x 359
812:2x 2x 7x 29
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 29 = 2320
Therefore, the value for common factors is 2320.
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 = 110767559649600/(1x2320)
LCM = 110767559649600/2320
LCM = 47744637780
Thus, we can understand that the LCM of 305,716,870,718,812 is 47744637780.
