Given numbers are 771,361,228,354
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 771,361,228,354 is 65686116.
Find LCM of 771,361,228,354 with Prime Factorization
| 2 | 771, 361, 228, 354 |
| 3 | 771, 361, 114, 177 |
| 19 | 257, 361, 38, 59 |
| 257, 19, 2, 59 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 19 x 257 x 19 x 2 x 59 = 65686116
Therefore, the lowest common multiple of 771,361,228,354 is 65686116.
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.
771 x 361 x 228 x 354 = 22464651672
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.
771 : 1, 3, 257, 771
361 : 1, 19, 361
228 : 1, 2, 3, 4, 6, 12, 19, 38, 57, 76, 114, 228
354 : 1, 2, 3, 6, 59, 118, 177, 354
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 771,361,228,354, is 1.
Now, the common factors can be found like this.
771:3x 257
361:19x 19
228:2x 2x 3x 19
354:2x 3x 59
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 19 = 342
Therefore, the value for common factors is 342.
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 = 22464651672/(1x342)
LCM = 22464651672/342
LCM = 65686116
Thus, we can understand that the LCM of 771,361,228,354 is 65686116.
