Given numbers are 549,543,407,403,871
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 549,543,407,403,871 is 1092006384183.
Find LCM of 549,543,407,403,871 with Prime Factorization
| 3 | 549, 543, 407, 403, 871 |
| 13 | 183, 181, 407, 403, 871 |
| 183, 181, 407, 31, 67 |
Multiply the prime numbers at the bottom and the left side.
3 x 13 x 183 x 181 x 407 x 31 x 67 = 1092006384183
Therefore, the lowest common multiple of 549,543,407,403,871 is 1092006384183.
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.
549 x 543 x 407 x 403 x 871 = 42588248983137
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.
549 : 1, 3, 9, 61, 183, 549
543 : 1, 3, 181, 543
407 : 1, 11, 37, 407
403 : 1, 13, 31, 403
871 : 1, 13, 67, 871
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 549,543,407,403,871, is 1.
Now, the common factors can be found like this.
549:3x 3x 61
543:3x 181
407:11x 37
403:13x 31
871:13x 67
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 13 = 39
Therefore, the value for common factors is 39.
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 = 42588248983137/(1x39)
LCM = 42588248983137/39
LCM = 1092006384183
Thus, we can understand that the LCM of 549,543,407,403,871 is 1092006384183.
