Given numbers are 254,278,385,139
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 254,278,385,139 is 13592810.
Find LCM of 254,278,385,139 with Prime Factorization
| 2 | 254, 278, 385, 139 |
| 139 | 127, 139, 385, 139 |
| 127, 1, 385, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 139 x 127 x 1 x 385 x 1 = 13592810
Therefore, the lowest common multiple of 254,278,385,139 is 13592810.
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.
254 x 278 x 385 x 139 = 3778801180
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.
254 : 1, 2, 127, 254
278 : 1, 2, 139, 278
385 : 1, 5, 7, 11, 35, 55, 77, 385
139 : 1, 139
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 254,278,385,139, is 1.
Now, the common factors can be found like this.
254:2x 127
278:2x 139
385:5x 7x 11
139:139
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 139 = 278
Therefore, the value for common factors is 278.
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 = 3778801180/(1x278)
LCM = 3778801180/278
LCM = 13592810
Thus, we can understand that the LCM of 254,278,385,139 is 13592810.
