Given numbers are 771,395,692,844,729
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 771,395,692,844,729 is 10805535563220.
Find LCM of 771,395,692,844,729 with Prime Factorization
| 2 | 771, 395, 692, 844, 729 |
| 2 | 771, 395, 346, 422, 729 |
| 3 | 771, 395, 173, 211, 729 |
| 257, 395, 173, 211, 243 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 257 x 395 x 173 x 211 x 243 = 10805535563220
Therefore, the lowest common multiple of 771,395,692,844,729 is 10805535563220.
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.
771 x 395 x 692 x 844 x 729 = 129666426758640
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.
771 : 1, 3, 257, 771
395 : 1, 5, 79, 395
692 : 1, 2, 4, 173, 346, 692
844 : 1, 2, 4, 211, 422, 844
729 : 1, 3, 9, 27, 81, 243, 729
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 771,395,692,844,729, is 1.
Now, the common factors can be found like this.
771:3x 257
395:5x 79
692:2x 2x 173
844:2x 2x 211
729:3x 3x 3x 3x 3x 3
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 3 = 12
Therefore, the value for common factors is 12.
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 = 129666426758640/(1x12)
LCM = 129666426758640/12
LCM = 10805535563220
Thus, we can understand that the LCM of 771,395,692,844,729 is 10805535563220.
