Given numbers are 193,342,398,969,781
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 193,342,398,969,781 is 174395970738.
Find LCM of 193,342,398,969,781 with Prime Factorization
2 | 193, 342, 398, 969, 781 |
3 | 193, 171, 199, 969, 781 |
19 | 193, 57, 199, 323, 781 |
193, 3, 199, 17, 781 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 19 x 193 x 3 x 199 x 17 x 781 = 174395970738
Therefore, the lowest common multiple of 193,342,398,969,781 is 174395970738.
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.
193 x 342 x 398 x 969 x 781 = 19881140664132
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.
193 : 1, 193
342 : 1, 2, 3, 6, 9, 18, 19, 38, 57, 114, 171, 342
398 : 1, 2, 199, 398
969 : 1, 3, 17, 19, 51, 57, 323, 969
781 : 1, 11, 71, 781
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 193,342,398,969,781, is 1.
Now, the common factors can be found like this.
193:193
342:2x 3x 3x 19
398:2x 199
969:3x 17x 19
781:11x 71
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 19 = 114
Therefore, the value for common factors is 114.
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 = 19881140664132/(1x114)
LCM = 19881140664132/114
LCM = 174395970738
Thus, we can understand that the LCM of 193,342,398,969,781 is 174395970738.
