Find LCM of 189,642,171,379,297 with Prime Factorization
| 3 | 189, 642, 171, 379, 297 |
| 3 | 63, 214, 57, 379, 99 |
| 3 | 21, 214, 19, 379, 33 |
| 7, 214, 19, 379, 11 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 3 x 7 x 214 x 19 x 379 x 11 = 3203768106
Therefore, the lowest common multiple of 189,642,171,379,297 is 3203768106.
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.
189 x 642 x 171 x 379 x 297 = 2335546949274
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.
189 : 1, 3, 7, 9, 21, 27, 63, 189
642 : 1, 2, 3, 6, 107, 214, 321, 642
171 : 1, 3, 9, 19, 57, 171
379 : 1, 379
297 : 1, 3, 9, 11, 27, 33, 99, 297
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 189,642,171,379,297, is 1.
Now, the common factors can be found like this.
189:3x 3x 3x 7
642:2x 3x 107
171:3x 3x 19
379:379
297:3x 3x 3x 11
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 3x 3 = 729
Therefore, the value for common factors is 729.
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 = 2335546949274/(1x729)
LCM = 2335546949274/729
LCM = 3203768106
Thus, we can understand that the LCM of 189,642,171,379,297 is 3203768106.
