Find LCM of 918,355,538,561,221 with Prime Factorization
2 | 918, 355, 538, 561, 221 |
3 | 459, 355, 269, 561, 221 |
17 | 153, 355, 269, 187, 221 |
9, 355, 269, 11, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 17 x 9 x 355 x 269 x 11 x 13 = 12536010630
Therefore, the lowest common multiple of 918,355,538,561,221 is 12536010630.
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.
918 x 355 x 538 x 561 x 221 = 21737442432420
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.
918 : 1, 2, 3, 6, 9, 17, 18, 27, 34, 51, 54, 102, 153, 306, 459, 918
355 : 1, 5, 71, 355
538 : 1, 2, 269, 538
561 : 1, 3, 11, 17, 33, 51, 187, 561
221 : 1, 13, 17, 221
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 918,355,538,561,221, is 1.
Now, the common factors can be found like this.
918:2x 3x 3x 3x 17
355:5x 71
538:2x 269
561:3x 11x 17
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.
2x 3x 17x 17 = 1734
Therefore, the value for common factors is 1734.
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 = 21737442432420/(1x1734)
LCM = 21737442432420/1734
LCM = 12536010630
Thus, we can understand that the LCM of 918,355,538,561,221 is 12536010630.
