Given numbers are 561,222,505,303,953
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 561,222,505,303,953 is 19979235210.
Find LCM of 561,222,505,303,953 with Prime Factorization
| 3 | 561, 222, 505, 303, 953 |
| 101 | 187, 74, 505, 101, 953 |
| 187, 74, 5, 1, 953 |
Multiply the prime numbers at the bottom and the left side.
3 x 101 x 187 x 74 x 5 x 1 x 953 = 19979235210
Therefore, the lowest common multiple of 561,222,505,303,953 is 19979235210.
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.
561 x 222 x 505 x 303 x 953 = 18161124805890
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.
561 : 1, 3, 11, 17, 33, 51, 187, 561
222 : 1, 2, 3, 6, 37, 74, 111, 222
505 : 1, 5, 101, 505
303 : 1, 3, 101, 303
953 : 1, 953
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 561,222,505,303,953, is 1.
Now, the common factors can be found like this.
561:3x 11x 17
222:2x 3x 37
505:5x 101
303:3x 101
953:953
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 101 = 909
Therefore, the value for common factors is 909.
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 = 18161124805890/(1x909)
LCM = 18161124805890/909
LCM = 19979235210
Thus, we can understand that the LCM of 561,222,505,303,953 is 19979235210.
