Find LCM of 274,729,663,189,161 with Prime Factorization
3 | 274, 729, 663, 189, 161 |
3 | 274, 243, 221, 63, 161 |
3 | 274, 81, 221, 21, 161 |
7 | 274, 27, 221, 7, 161 |
274, 27, 221, 1, 23 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 3 x 7 x 274 x 27 x 221 x 1 x 23 = 7107162426
Therefore, the lowest common multiple of 274,729,663,189,161 is 7107162426.
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.
274 x 729 x 663 x 189 x 161 = 4029761095542
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.
274 : 1, 2, 137, 274
729 : 1, 3, 9, 27, 81, 243, 729
663 : 1, 3, 13, 17, 39, 51, 221, 663
189 : 1, 3, 7, 9, 21, 27, 63, 189
161 : 1, 7, 23, 161
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 274,729,663,189,161, is 1.
Now, the common factors can be found like this.
274:2x 137
729:3x 3x 3x 3x 3x 3
663:3x 13x 17
189:3x 3x 3x 7
161:7x 23
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 3x 3x 7 = 567
Therefore, the value for common factors is 567.
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 = 4029761095542/(1x567)
LCM = 4029761095542/567
LCM = 7107162426
Thus, we can understand that the LCM of 274,729,663,189,161 is 7107162426.
