Given numbers are 655,869,261,955,435
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 655,869,261,955,435 is 28374939945.
Find LCM of 655,869,261,955,435 with Prime Factorization
3 | 655, 869, 261, 955, 435 |
5 | 655, 869, 87, 955, 145 |
29 | 131, 869, 87, 191, 29 |
131, 869, 3, 191, 1 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 29 x 131 x 869 x 3 x 191 x 1 = 28374939945
Therefore, the lowest common multiple of 655,869,261,955,435 is 28374939945.
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.
655 x 869 x 261 x 955 x 435 = 61715494380375
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.
655 : 1, 5, 131, 655
869 : 1, 11, 79, 869
261 : 1, 3, 9, 29, 87, 261
955 : 1, 5, 191, 955
435 : 1, 3, 5, 15, 29, 87, 145, 435
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 655,869,261,955,435, is 1.
Now, the common factors can be found like this.
655:5x 131
869:11x 79
261:3x 3x 29
955:5x 191
435:3x 5x 29
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5x 5x 29 = 2175
Therefore, the value for common factors is 2175.
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 = 61715494380375/(1x2175)
LCM = 61715494380375/2175
LCM = 28374939945
Thus, we can understand that the LCM of 655,869,261,955,435 is 28374939945.
