Given numbers are 705,695,659,847
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 705,695,659,847 is 54698163135.
Find LCM of 705,695,659,847 with Prime Factorization
| 5 | 705, 695, 659, 847 |
| 141, 139, 659, 847 |
Multiply the prime numbers at the bottom and the left side.
5 x 141 x 139 x 659 x 847 = 54698163135
Therefore, the lowest common multiple of 705,695,659,847 is 54698163135.
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.
705 x 695 x 659 x 847 = 273490815675
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.
705 : 1, 3, 5, 15, 47, 141, 235, 705
695 : 1, 5, 139, 695
659 : 1, 659
847 : 1, 7, 11, 77, 121, 847
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 705,695,659,847, is 1.
Now, the common factors can be found like this.
705:3x 5x 47
695:5x 139
659:659
847:7x 11x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5 = 5
Therefore, the value for common factors is 5.
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 = 273490815675/(1x5)
LCM = 273490815675/5
LCM = 54698163135
Thus, we can understand that the LCM of 705,695,659,847 is 54698163135.
