Find LCM of 975,187,170,150,428 with Prime Factorization
| 2 | 975, 187, 170, 150, 428 |
| 3 | 975, 187, 85, 75, 214 |
| 5 | 325, 187, 85, 25, 214 |
| 5 | 65, 187, 17, 5, 214 |
| 17 | 13, 187, 17, 1, 214 |
| 13, 11, 1, 1, 214 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 5 x 17 x 13 x 11 x 1 x 1 x 214 = 78035100
Therefore, the lowest common multiple of 975,187,170,150,428 is 78035100.
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.
975 x 187 x 170 x 150 x 428 = 1989895050000
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.
975 : 1, 3, 5, 13, 15, 25, 39, 65, 75, 195, 325, 975
187 : 1, 11, 17, 187
170 : 1, 2, 5, 10, 17, 34, 85, 170
150 : 1, 2, 3, 5, 6, 10, 15, 25, 30, 50, 75, 150
428 : 1, 2, 4, 107, 214, 428
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 975,187,170,150,428, is 1.
Now, the common factors can be found like this.
975:3x 5x 5x 13
187:11x 17
170:2x 5x 17
150:2x 3x 5x 5
428:2x 2x 107
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 3x 5x 5x 5x 17 = 25500
Therefore, the value for common factors is 25500.
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 = 1989895050000/(1x25500)
LCM = 1989895050000/25500
LCM = 78035100
Thus, we can understand that the LCM of 975,187,170,150,428 is 78035100.
