Given numbers are 555,492,362,654,644
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 555,492,362,654,644 is 289113106380.
Find LCM of 555,492,362,654,644 with Prime Factorization
| 2 | 555, 492, 362, 654, 644 |
| 2 | 555, 246, 181, 327, 322 |
| 3 | 555, 123, 181, 327, 161 |
| 185, 41, 181, 109, 161 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 185 x 41 x 181 x 109 x 161 = 289113106380
Therefore, the lowest common multiple of 555,492,362,654,644 is 289113106380.
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.
555 x 492 x 362 x 654 x 644 = 41632287318720
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.
555 : 1, 3, 5, 15, 37, 111, 185, 555
492 : 1, 2, 3, 4, 6, 12, 41, 82, 123, 164, 246, 492
362 : 1, 2, 181, 362
654 : 1, 2, 3, 6, 109, 218, 327, 654
644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 555,492,362,654,644, is 1.
Now, the common factors can be found like this.
555:3x 5x 37
492:2x 2x 3x 41
362:2x 181
654:2x 3x 109
644:2x 2x 7x 23
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 3x 3 = 144
Therefore, the value for common factors is 144.
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 = 41632287318720/(1x144)
LCM = 41632287318720/144
LCM = 289113106380
Thus, we can understand that the LCM of 555,492,362,654,644 is 289113106380.
