Find LCM of 361,618,297,789,154 with Prime Factorization
| 2 | 361, 618, 297, 789, 154 |
| 3 | 361, 309, 297, 789, 77 |
| 11 | 361, 103, 99, 263, 77 |
| 361, 103, 9, 263, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 361 x 103 x 9 x 263 x 7 = 40661618382
Therefore, the lowest common multiple of 361,618,297,789,154 is 40661618382.
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.
361 x 618 x 297 x 789 x 154 = 8051000439636
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.
361 : 1, 19, 361
618 : 1, 2, 3, 6, 103, 206, 309, 618
297 : 1, 3, 9, 11, 27, 33, 99, 297
789 : 1, 3, 263, 789
154 : 1, 2, 7, 11, 14, 22, 77, 154
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 361,618,297,789,154, is 1.
Now, the common factors can be found like this.
361:19x 19
618:2x 3x 103
297:3x 3x 3x 11
789:3x 263
154:2x 7x 11
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 3x 11 = 198
Therefore, the value for common factors is 198.
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 = 8051000439636/(1x198)
LCM = 8051000439636/198
LCM = 40661618382
Thus, we can understand that the LCM of 361,618,297,789,154 is 40661618382.
