Given numbers are 866,965,956,740,421
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 866,965,956,740,421 is 6222385616140.
Find LCM of 866,965,956,740,421 with Prime Factorization
2 | 866, 965, 956, 740, 421 |
2 | 433, 965, 478, 370, 421 |
5 | 433, 965, 239, 185, 421 |
433, 193, 239, 37, 421 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 433 x 193 x 239 x 37 x 421 = 6222385616140
Therefore, the lowest common multiple of 866,965,956,740,421 is 6222385616140.
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.
866 x 965 x 956 x 740 x 421 = 248895424645600
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.
866 : 1, 2, 433, 866
965 : 1, 5, 193, 965
956 : 1, 2, 4, 239, 478, 956
740 : 1, 2, 4, 5, 10, 20, 37, 74, 148, 185, 370, 740
421 : 1, 421
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 866,965,956,740,421, is 1.
Now, the common factors can be found like this.
866:2x 433
965:5x 193
956:2x 2x 239
740:2x 2x 5x 37
421:421
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 2x 5 = 40
Therefore, the value for common factors is 40.
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 = 248895424645600/(1x40)
LCM = 248895424645600/40
LCM = 6222385616140
Thus, we can understand that the LCM of 866,965,956,740,421 is 6222385616140.
