Given numbers are 347,686,759,862
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 347,686,759,862 is 77870441418.
Find LCM of 347,686,759,862 with Prime Factorization
| 2 | 347, 686, 759, 862 |
| 347, 343, 759, 431 |
Multiply the prime numbers at the bottom and the left side.
2 x 347 x 343 x 759 x 431 = 77870441418
Therefore, the lowest common multiple of 347,686,759,862 is 77870441418.
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.
347 x 686 x 759 x 862 = 155740882836
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.
347 : 1, 347
686 : 1, 2, 7, 14, 49, 98, 343, 686
759 : 1, 3, 11, 23, 33, 69, 253, 759
862 : 1, 2, 431, 862
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 347,686,759,862, is 1.
Now, the common factors can be found like this.
347:347
686:2x 7x 7x 7
759:3x 11x 23
862:2x 431
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2 = 2
Therefore, the value for common factors is 2.
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 = 155740882836/(1x2)
LCM = 155740882836/2
LCM = 77870441418
Thus, we can understand that the LCM of 347,686,759,862 is 77870441418.
