Given numbers are 855,649,171,154
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 855,649,171,154 is 7768530.
Find LCM of 855,649,171,154 with Prime Factorization
| 3 | 855, 649, 171, 154 |
| 3 | 285, 649, 57, 154 |
| 11 | 95, 649, 19, 154 |
| 19 | 95, 59, 19, 14 |
| 5, 59, 1, 14 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 11 x 19 x 5 x 59 x 1 x 14 = 7768530
Therefore, the lowest common multiple of 855,649,171,154 is 7768530.
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.
855 x 649 x 171 x 154 = 14612604930
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.
855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855
649 : 1, 11, 59, 649
171 : 1, 3, 9, 19, 57, 171
154 : 1, 2, 7, 11, 14, 22, 77, 154
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 855,649,171,154, is 1.
Now, the common factors can be found like this.
855:3x 3x 5x 19
649:11x 59
171:3x 3x 19
154:2x 7x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 11x 19 = 1881
Therefore, the value for common factors is 1881.
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 = 14612604930/(1x1881)
LCM = 14612604930/1881
LCM = 7768530
Thus, we can understand that the LCM of 855,649,171,154 is 7768530.
