Find LCM of 342,187,872,128,605 with Prime Factorization
2 | 342, 187, 872, 128, 605 |
2 | 171, 187, 436, 64, 605 |
2 | 171, 187, 218, 32, 605 |
11 | 171, 187, 109, 16, 605 |
171, 17, 109, 16, 55 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 11 x 171 x 17 x 109 x 16 x 55 = 24537870720
Therefore, the lowest common multiple of 342,187,872,128,605 is 24537870720.
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.
342 x 187 x 872 x 128 x 605 = 4318665246720
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.
342 : 1, 2, 3, 6, 9, 18, 19, 38, 57, 114, 171, 342
187 : 1, 11, 17, 187
872 : 1, 2, 4, 8, 109, 218, 436, 872
128 : 1, 2, 4, 8, 16, 32, 64, 128
605 : 1, 5, 11, 55, 121, 605
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 342,187,872,128,605, is 1.
Now, the common factors can be found like this.
342:2x 3x 3x 19
187:11x 17
872:2x 2x 2x 109
128:2x 2x 2x 2x 2x 2x 2
605:5x 11x 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 2x 2x 2x 11 = 176
Therefore, the value for common factors is 176.
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 = 4318665246720/(1x176)
LCM = 4318665246720/176
LCM = 24537870720
Thus, we can understand that the LCM of 342,187,872,128,605 is 24537870720.
