Given numbers are 127,961,221,663
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 127,961,221,663 is 80917161.
Find LCM of 127,961,221,663 with Prime Factorization
13 | 127, 961, 221, 663 |
17 | 127, 961, 17, 51 |
127, 961, 1, 3 |
Multiply the prime numbers at the bottom and the left side.
13 x 17 x 127 x 961 x 1 x 3 = 80917161
Therefore, the lowest common multiple of 127,961,221,663 is 80917161.
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.
127 x 961 x 221 x 663 = 17882692581
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.
127 : 1, 127
961 : 1, 31, 961
221 : 1, 13, 17, 221
663 : 1, 3, 13, 17, 39, 51, 221, 663
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 127,961,221,663, is 1.
Now, the common factors can be found like this.
127:127
961:31x 31
221:13x 17
663:3x 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.
13x 17 = 221
Therefore, the value for common factors is 221.
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 = 17882692581/(1x221)
LCM = 17882692581/221
LCM = 80917161
Thus, we can understand that the LCM of 127,961,221,663 is 80917161.
