Given numbers are 195,661,802,782
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 195,661,802,782 is 40419151890.
Find LCM of 195,661,802,782 with Prime Factorization
| 2 | 195, 661, 802, 782 |
| 195, 661, 401, 391 |
Multiply the prime numbers at the bottom and the left side.
2 x 195 x 661 x 401 x 391 = 40419151890
Therefore, the lowest common multiple of 195,661,802,782 is 40419151890.
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.
195 x 661 x 802 x 782 = 80838303780
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.
195 : 1, 3, 5, 13, 15, 39, 65, 195
661 : 1, 661
802 : 1, 2, 401, 802
782 : 1, 2, 17, 23, 34, 46, 391, 782
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 195,661,802,782, is 1.
Now, the common factors can be found like this.
195:3x 5x 13
661:661
802:2x 401
782:2x 17x 23
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 = 80838303780/(1x2)
LCM = 80838303780/2
LCM = 40419151890
Thus, we can understand that the LCM of 195,661,802,782 is 40419151890.
