Given numbers are 647,398,351,226
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 647,398,351,226 is 10213460478.
Find LCM of 647,398,351,226 with Prime Factorization
| 2 | 647, 398, 351, 226 |
| 647, 199, 351, 113 |
Multiply the prime numbers at the bottom and the left side.
2 x 647 x 199 x 351 x 113 = 10213460478
Therefore, the lowest common multiple of 647,398,351,226 is 10213460478.
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.
647 x 398 x 351 x 226 = 20426920956
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.
647 : 1, 647
398 : 1, 2, 199, 398
351 : 1, 3, 9, 13, 27, 39, 117, 351
226 : 1, 2, 113, 226
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 647,398,351,226, is 1.
Now, the common factors can be found like this.
647:647
398:2x 199
351:3x 3x 3x 13
226:2x 113
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2 = 2
Therefore, the value for common factors is 2.
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 = 20426920956/(1x2)
LCM = 20426920956/2
LCM = 10213460478
Thus, we can understand that the LCM of 647,398,351,226 is 10213460478.
