Given numbers are 105,407,819,201,698
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 105,407,819,201,698 is 77943255390.
Find LCM of 105,407,819,201,698 with Prime Factorization
3 | 105, 407, 819, 201, 698 |
7 | 35, 407, 273, 67, 698 |
5, 407, 39, 67, 698 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 5 x 407 x 39 x 67 x 698 = 77943255390
Therefore, the lowest common multiple of 105,407,819,201,698 is 77943255390.
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.
105 x 407 x 819 x 201 x 698 = 4910425089570
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.
105 : 1, 3, 5, 7, 15, 21, 35, 105
407 : 1, 11, 37, 407
819 : 1, 3, 7, 9, 13, 21, 39, 63, 91, 117, 273, 819
201 : 1, 3, 67, 201
698 : 1, 2, 349, 698
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 105,407,819,201,698, is 1.
Now, the common factors can be found like this.
105:3x 5x 7
407:11x 37
819:3x 3x 7x 13
201:3x 67
698:2x 349
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 7 = 63
Therefore, the value for common factors is 63.
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 = 4910425089570/(1x63)
LCM = 4910425089570/63
LCM = 77943255390
Thus, we can understand that the LCM of 105,407,819,201,698 is 77943255390.
