Given numbers are 254,779,628,228
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 254,779,628,228 is 186389772.
Find LCM of 254,779,628,228 with Prime Factorization
| 2 | 254, 779, 628, 228 |
| 2 | 127, 779, 314, 114 |
| 19 | 127, 779, 157, 57 |
| 127, 41, 157, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 19 x 127 x 41 x 157 x 3 = 186389772
Therefore, the lowest common multiple of 254,779,628,228 is 186389772.
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 779 x 628 x 228 = 28331245344
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
779 : 1, 19, 41, 779
628 : 1, 2, 4, 157, 314, 628
228 : 1, 2, 3, 4, 6, 12, 19, 38, 57, 76, 114, 228
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 254,779,628,228, is 1.
Now, the common factors can be found like this.
254:2x 127
779:19x 41
628:2x 2x 157
228:2x 2x 3x 19
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 19 = 152
Therefore, the value for common factors is 152.
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 = 28331245344/(1x152)
LCM = 28331245344/152
LCM = 186389772
Thus, we can understand that the LCM of 254,779,628,228 is 186389772.
