Given numbers are 654,803,978,164
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 654,803,978,164 is 7019315292.
Find LCM of 654,803,978,164 with Prime Factorization
| 2 | 654, 803, 978, 164 |
| 3 | 327, 803, 489, 82 |
| 109, 803, 163, 82 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 109 x 803 x 163 x 82 = 7019315292
Therefore, the lowest common multiple of 654,803,978,164 is 7019315292.
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.
654 x 803 x 978 x 164 = 84231783504
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.
654 : 1, 2, 3, 6, 109, 218, 327, 654
803 : 1, 11, 73, 803
978 : 1, 2, 3, 6, 163, 326, 489, 978
164 : 1, 2, 4, 41, 82, 164
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 654,803,978,164, is 1.
Now, the common factors can be found like this.
654:2x 3x 109
803:11x 73
978:2x 3x 163
164:2x 2x 41
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 3 = 12
Therefore, the value for common factors is 12.
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 = 84231783504/(1x12)
LCM = 84231783504/12
LCM = 7019315292
Thus, we can understand that the LCM of 654,803,978,164 is 7019315292.
