Given numbers are 192,870,144,248,221
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 192,870,144,248,221 is 572195520.
Find LCM of 192,870,144,248,221 with Prime Factorization
| 2 | 192, 870, 144, 248, 221 |
| 2 | 96, 435, 72, 124, 221 |
| 2 | 48, 435, 36, 62, 221 |
| 2 | 24, 435, 18, 31, 221 |
| 3 | 12, 435, 9, 31, 221 |
| 4, 145, 3, 31, 221 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 4 x 145 x 3 x 31 x 221 = 572195520
Therefore, the lowest common multiple of 192,870,144,248,221 is 572195520.
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.
192 x 870 x 144 x 248 x 221 = 1318338478080
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.
192 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 192
870 : 1, 2, 3, 5, 6, 10, 15, 29, 30, 58, 87, 145, 174, 290, 435, 870
144 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 36, 48, 72, 144
248 : 1, 2, 4, 8, 31, 62, 124, 248
221 : 1, 13, 17, 221
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 192,870,144,248,221, is 1.
Now, the common factors can be found like this.
192:2x 2x 2x 2x 2x 2x 3
870:2x 3x 5x 29
144:2x 2x 2x 2x 3x 3
248:2x 2x 2x 31
221:13x 17
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 2x 2x 2x 2x 2x 3x 3 = 2304
Therefore, the value for common factors is 2304.
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 = 1318338478080/(1x2304)
LCM = 1318338478080/2304
LCM = 572195520
Thus, we can understand that the LCM of 192,870,144,248,221 is 572195520.
