Given numbers are 163,763,133,665
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 163,763,133,665 is 11815055.
Find LCM of 163,763,133,665 with Prime Factorization
| 7 | 163, 763, 133, 665 |
| 19 | 163, 109, 19, 95 |
| 163, 109, 1, 5 |
Multiply the prime numbers at the bottom and the left side.
7 x 19 x 163 x 109 x 1 x 5 = 11815055
Therefore, the lowest common multiple of 163,763,133,665 is 11815055.
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.
163 x 763 x 133 x 665 = 10999816205
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.
163 : 1, 163
763 : 1, 7, 109, 763
133 : 1, 7, 19, 133
665 : 1, 5, 7, 19, 35, 95, 133, 665
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 163,763,133,665, is 1.
Now, the common factors can be found like this.
163:163
763:7x 109
133:7x 19
665:5x 7x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
7x 7x 19 = 931
Therefore, the value for common factors is 931.
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 = 10999816205/(1x931)
LCM = 10999816205/931
LCM = 11815055
Thus, we can understand that the LCM of 163,763,133,665 is 11815055.
