Given numbers are 501,441,861,221
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 501,441,861,221 is 667315467.
Find LCM of 501,441,861,221 with Prime Factorization
3 | 501, 441, 861, 221 |
7 | 167, 147, 287, 221 |
167, 21, 41, 221 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 167 x 21 x 41 x 221 = 667315467
Therefore, the lowest common multiple of 501,441,861,221 is 667315467.
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.
501 x 441 x 861 x 221 = 42040874421
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.
501 : 1, 3, 167, 501
441 : 1, 3, 7, 9, 21, 49, 63, 147, 441
861 : 1, 3, 7, 21, 41, 123, 287, 861
221 : 1, 13, 17, 221
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 501,441,861,221, is 1.
Now, the common factors can be found like this.
501:3x 167
441:3x 3x 7x 7
861:3x 7x 41
221:13x 17
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 7 = 63
Therefore, the value for common factors is 63.
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 = 42040874421/(1x63)
LCM = 42040874421/63
LCM = 667315467
Thus, we can understand that the LCM of 501,441,861,221 is 667315467.
