Given numbers are 781,349,995,231
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 781,349,995,231 is 5695329255.
Find LCM of 781,349,995,231 with Prime Factorization
| 11 | 781, 349, 995, 231 |
| 71, 349, 995, 21 |
Multiply the prime numbers at the bottom and the left side.
11 x 71 x 349 x 995 x 21 = 5695329255
Therefore, the lowest common multiple of 781,349,995,231 is 5695329255.
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.
781 x 349 x 995 x 231 = 62648621805
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.
781 : 1, 11, 71, 781
349 : 1, 349
995 : 1, 5, 199, 995
231 : 1, 3, 7, 11, 21, 33, 77, 231
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 781,349,995,231, is 1.
Now, the common factors can be found like this.
781:11x 71
349:349
995:5x 199
231:3x 7x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
11 = 11
Therefore, the value for common factors is 11.
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 = 62648621805/(1x11)
LCM = 62648621805/11
LCM = 5695329255
Thus, we can understand that the LCM of 781,349,995,231 is 5695329255.
