The LCM of 628,364,361,282,147 is 20362232436.
Find LCM of 628,364,361,282,147 with Prime Factorization
| 2 | 628, 364, 361, 282, 147 |
| 2 | 314, 182, 361, 141, 147 |
| 3 | 157, 91, 361, 141, 147 |
| 7 | 157, 91, 361, 47, 49 |
| 157, 13, 361, 47, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 157 x 13 x 361 x 47 x 7 = 20362232436
Therefore, the lowest common multiple of 628,364,361,282,147 is 20362232436.
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.
628 x 364 x 361 x 282 x 147 = 3420855049248
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.
628 : 1, 2, 4, 157, 314, 628
364 : 1, 2, 4, 7, 13, 14, 26, 28, 52, 91, 182, 364
361 : 1, 19, 361
282 : 1, 2, 3, 6, 47, 94, 141, 282
147 : 1, 3, 7, 21, 49, 147
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 628,364,361,282,147, is 1.
Now, the common factors can be found like this.
628:2x 2x 157
364:2x 2x 7x 13
361:19x 19
282:2x 3x 47
147:3x 7x 7
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 3x 7 = 168
Therefore, the value for common factors is 168.
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 = 3420855049248/(1x168)
LCM = 3420855049248/168
LCM = 20362232436
Thus, we can understand that the LCM of 628,364,361,282,147 is 20362232436.
