The LCM of 223,549,646,171 is 79087842.
Find LCM of 223,549,646,171 with Prime Factorization
| 3 | 223, 549, 646, 171 |
| 3 | 223, 183, 646, 57 |
| 19 | 223, 61, 646, 19 |
| 223, 61, 34, 1 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 19 x 223 x 61 x 34 x 1 = 79087842
Therefore, the lowest common multiple of 223,549,646,171 is 79087842.
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.
223 x 549 x 646 x 171 = 13524020982
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.
223 : 1, 223
549 : 1, 3, 9, 61, 183, 549
646 : 1, 2, 17, 19, 34, 38, 323, 646
171 : 1, 3, 9, 19, 57, 171
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 223,549,646,171, is 1.
Now, the common factors can be found like this.
223:223
549:3x 3x 61
646:2x 17x 19
171:3x 3x 19
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 19 = 171
Therefore, the value for common factors is 171.
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 = 13524020982/(1x171)
LCM = 13524020982/171
LCM = 79087842
Thus, we can understand that the LCM of 223,549,646,171 is 79087842.
