Given numbers are 260,364,980,805
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 260,364,980,805 is 293020.
Find LCM of 260,364,980,805 with Prime Factorization
| 2 | 260, 364, 980, 805 |
| 2 | 130, 182, 490, 805 |
| 5 | 65, 91, 245, 805 |
| 7 | 13, 91, 49, 161 |
| 13 | 13, 13, 7, 23 |
| 1, 1, 7, 23 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 7 x 13 x 1 x 1 x 7 x 23 = 293020
Therefore, the lowest common multiple of 260,364,980,805 is 293020.
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.
260 x 364 x 980 x 805 = 74661496000
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.
260 : 1, 2, 4, 5, 10, 13, 20, 26, 52, 65, 130, 260
364 : 1, 2, 4, 7, 13, 14, 26, 28, 52, 91, 182, 364
980 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 49, 70, 98, 140, 196, 245, 490, 980
805 : 1, 5, 7, 23, 35, 115, 161, 805
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 260,364,980,805, is 1.
Now, the common factors can be found like this.
260:2x 2x 5x 13
364:2x 2x 7x 13
980:2x 2x 5x 7x 7
805:5x 7x 23
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 5x 7x 7x 13 = 254800
Therefore, the value for common factors is 254800.
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 = 74661496000/(1x254800)
LCM = 74661496000/254800
LCM = 293020
Thus, we can understand that the LCM of 260,364,980,805 is 293020.
