Given numbers are 375,385,978,189
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 375,385,978,189 is 84719250.
Find LCM of 375,385,978,189 with Prime Factorization
| 3 | 375, 385, 978, 189 |
| 5 | 125, 385, 326, 63 |
| 7 | 25, 77, 326, 63 |
| 25, 11, 326, 9 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 7 x 25 x 11 x 326 x 9 = 84719250
Therefore, the lowest common multiple of 375,385,978,189 is 84719250.
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.
375 x 385 x 978 x 189 = 26686563750
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.
375 : 1, 3, 5, 15, 25, 75, 125, 375
385 : 1, 5, 7, 11, 35, 55, 77, 385
978 : 1, 2, 3, 6, 163, 326, 489, 978
189 : 1, 3, 7, 9, 21, 27, 63, 189
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 375,385,978,189, is 1.
Now, the common factors can be found like this.
375:3x 5x 5x 5
385:5x 7x 11
978:2x 3x 163
189:3x 3x 3x 7
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 5x 7 = 315
Therefore, the value for common factors is 315.
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 = 26686563750/(1x315)
LCM = 26686563750/315
LCM = 84719250
Thus, we can understand that the LCM of 375,385,978,189 is 84719250.
