Given numbers are 278,938,139,225
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 278,938,139,225 is 29335950.
Find LCM of 278,938,139,225 with Prime Factorization
| 2 | 278, 938, 139, 225 |
| 139 | 139, 469, 139, 225 |
| 1, 469, 1, 225 |
Multiply the prime numbers at the bottom and the left side.
2 x 139 x 1 x 469 x 1 x 225 = 29335950
Therefore, the lowest common multiple of 278,938,139,225 is 29335950.
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.
278 x 938 x 139 x 225 = 8155394100
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.
278 : 1, 2, 139, 278
938 : 1, 2, 7, 14, 67, 134, 469, 938
139 : 1, 139
225 : 1, 3, 5, 9, 15, 25, 45, 75, 225
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 278,938,139,225, is 1.
Now, the common factors can be found like this.
278:2x 139
938:2x 7x 67
139:139
225:3x 3x 5x 5
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 = 8155394100/(1x278)
LCM = 8155394100/278
LCM = 29335950
Thus, we can understand that the LCM of 278,938,139,225 is 29335950.
