Given numbers are 715,646,969,263
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 715,646,969,263 is 364431210.
Find LCM of 715,646,969,263 with Prime Factorization
| 17 | 715, 646, 969, 263 |
| 19 | 715, 38, 57, 263 |
| 715, 2, 3, 263 |
Multiply the prime numbers at the bottom and the left side.
17 x 19 x 715 x 2 x 3 x 263 = 364431210
Therefore, the lowest common multiple of 715,646,969,263 is 364431210.
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.
715 x 646 x 969 x 263 = 117711280830
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.
715 : 1, 5, 11, 13, 55, 65, 143, 715
646 : 1, 2, 17, 19, 34, 38, 323, 646
969 : 1, 3, 17, 19, 51, 57, 323, 969
263 : 1, 263
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 715,646,969,263, is 1.
Now, the common factors can be found like this.
715:5x 11x 13
646:2x 17x 19
969:3x 17x 19
263:263
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
17x 19 = 323
Therefore, the value for common factors is 323.
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 = 117711280830/(1x323)
LCM = 117711280830/323
LCM = 364431210
Thus, we can understand that the LCM of 715,646,969,263 is 364431210.
