Given numbers are 513,803,646,251
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 513,803,646,251 is 3515487426.
Find LCM of 513,803,646,251 with Prime Factorization
| 19 | 513, 803, 646, 251 |
| 27, 803, 34, 251 |
Multiply the prime numbers at the bottom and the left side.
19 x 27 x 803 x 34 x 251 = 3515487426
Therefore, the lowest common multiple of 513,803,646,251 is 3515487426.
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.
513 x 803 x 646 x 251 = 66794261094
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.
513 : 1, 3, 9, 19, 27, 57, 171, 513
803 : 1, 11, 73, 803
646 : 1, 2, 17, 19, 34, 38, 323, 646
251 : 1, 251
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 513,803,646,251, is 1.
Now, the common factors can be found like this.
513:3x 3x 3x 19
803:11x 73
646:2x 17x 19
251:251
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
19 = 19
Therefore, the value for common factors is 19.
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 = 66794261094/(1x19)
LCM = 66794261094/19
LCM = 3515487426
Thus, we can understand that the LCM of 513,803,646,251 is 3515487426.
