Given numbers are 498,549,913,781
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 498,549,913,781 is 71175654.
Find LCM of 498,549,913,781 with Prime Factorization
| 3 | 498, 549, 913, 781 |
| 11 | 166, 183, 913, 781 |
| 83 | 166, 183, 83, 71 |
| 2, 183, 1, 71 |
Multiply the prime numbers at the bottom and the left side.
3 x 11 x 83 x 2 x 183 x 1 x 71 = 71175654
Therefore, the lowest common multiple of 498,549,913,781 is 71175654.
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.
498 x 549 x 913 x 781 = 194950116306
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.
498 : 1, 2, 3, 6, 83, 166, 249, 498
549 : 1, 3, 9, 61, 183, 549
913 : 1, 11, 83, 913
781 : 1, 11, 71, 781
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 498,549,913,781, is 1.
Now, the common factors can be found like this.
498:2x 3x 83
549:3x 3x 61
913:11x 83
781:11x 71
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 11x 83 = 2739
Therefore, the value for common factors is 2739.
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 = 194950116306/(1x2739)
LCM = 194950116306/2739
LCM = 71175654
Thus, we can understand that the LCM of 498,549,913,781 is 71175654.
