Given numbers are 781,994,705,499
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 781,994,705,499 is 3846526530.
Find LCM of 781,994,705,499 with Prime Factorization
71 | 781, 994, 705, 499 |
11, 14, 705, 499 |
Multiply the prime numbers at the bottom and the left side.
71 x 11 x 14 x 705 x 499 = 3846526530
Therefore, the lowest common multiple of 781,994,705,499 is 3846526530.
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.
781 x 994 x 705 x 499 = 273103383630
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.
781 : 1, 11, 71, 781
994 : 1, 2, 7, 14, 71, 142, 497, 994
705 : 1, 3, 5, 15, 47, 141, 235, 705
499 : 1, 499
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 781,994,705,499, is 1.
Now, the common factors can be found like this.
781:11x 71
994:2x 7x 71
705:3x 5x 47
499:499
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
71 = 71
Therefore, the value for common factors is 71.
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 = 273103383630/(1x71)
LCM = 273103383630/71
LCM = 3846526530
Thus, we can understand that the LCM of 781,994,705,499 is 3846526530.
