Given numbers are 549,877,781,642,107
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 549,877,781,642,107 is 80470508382.
Find LCM of 549,877,781,642,107 with Prime Factorization
| 3 | 549, 877, 781, 642, 107 |
| 107 | 183, 877, 781, 214, 107 |
| 183, 877, 781, 2, 1 |
Multiply the prime numbers at the bottom and the left side.
3 x 107 x 183 x 877 x 781 x 2 x 1 = 80470508382
Therefore, the lowest common multiple of 549,877,781,642,107 is 80470508382.
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 877 x 781 x 642 x 107 = 25831033190622
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
877 : 1, 877
781 : 1, 11, 71, 781
642 : 1, 2, 3, 6, 107, 214, 321, 642
107 : 1, 107
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 549,877,781,642,107, is 1.
Now, the common factors can be found like this.
549:3x 3x 61
877:877
781:11x 71
642:2x 3x 107
107:107
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 107 = 321
Therefore, the value for common factors is 321.
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 = 25831033190622/(1x321)
LCM = 25831033190622/321
LCM = 80470508382
Thus, we can understand that the LCM of 549,877,781,642,107 is 80470508382.
