Given numbers are 711,422,780,759,902
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 711,422,780,759,902 is 404603636580.
Find LCM of 711,422,780,759,902 with Prime Factorization
| 2 | 711, 422, 780, 759, 902 |
| 3 | 711, 211, 390, 759, 451 |
| 11 | 237, 211, 130, 253, 451 |
| 237, 211, 130, 23, 41 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 237 x 211 x 130 x 23 x 41 = 404603636580
Therefore, the lowest common multiple of 711,422,780,759,902 is 404603636580.
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.
711 x 422 x 780 x 759 x 902 = 160223040085680
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.
711 : 1, 3, 9, 79, 237, 711
422 : 1, 2, 211, 422
780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780
759 : 1, 3, 11, 23, 33, 69, 253, 759
902 : 1, 2, 11, 22, 41, 82, 451, 902
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 711,422,780,759,902, is 1.
Now, the common factors can be found like this.
711:3x 3x 79
422:2x 211
780:2x 2x 3x 5x 13
759:3x 11x 23
902:2x 11x 41
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 3x 3x 11 = 396
Therefore, the value for common factors is 396.
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 = 160223040085680/(1x396)
LCM = 160223040085680/396
LCM = 404603636580
Thus, we can understand that the LCM of 711,422,780,759,902 is 404603636580.
