Given numbers are 644,402,358,322,263
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 644,402,358,322,263 is 6093835188.
Find LCM of 644,402,358,322,263 with Prime Factorization
| 2 | 644, 402, 358, 322, 263 |
| 7 | 322, 201, 179, 161, 263 |
| 23 | 46, 201, 179, 23, 263 |
| 2, 201, 179, 1, 263 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 23 x 2 x 201 x 179 x 1 x 263 = 6093835188
Therefore, the lowest common multiple of 644,402,358,322,263 is 6093835188.
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.
644 x 402 x 358 x 322 x 263 = 7848859722144
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.
644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644
402 : 1, 2, 3, 6, 67, 134, 201, 402
358 : 1, 2, 179, 358
322 : 1, 2, 7, 14, 23, 46, 161, 322
263 : 1, 263
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 644,402,358,322,263, is 1.
Now, the common factors can be found like this.
644:2x 2x 7x 23
402:2x 3x 67
358:2x 179
322:2x 7x 23
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.
2x 2x 2x 7x 23 = 1288
Therefore, the value for common factors is 1288.
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 = 7848859722144/(1x1288)
LCM = 7848859722144/1288
LCM = 6093835188
Thus, we can understand that the LCM of 644,402,358,322,263 is 6093835188.
