Given numbers are 991,362,437,943,860
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 991,362,437,943,860 is 2763859578020.
Find LCM of 991,362,437,943,860 with Prime Factorization
| 2 | 991, 362, 437, 943, 860 |
| 23 | 991, 181, 437, 943, 430 |
| 991, 181, 19, 41, 430 |
Multiply the prime numbers at the bottom and the left side.
2 x 23 x 991 x 181 x 19 x 41 x 430 = 2763859578020
Therefore, the lowest common multiple of 991,362,437,943,860 is 2763859578020.
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.
991 x 362 x 437 x 943 x 860 = 127137540588920
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.
991 : 1, 991
362 : 1, 2, 181, 362
437 : 1, 19, 23, 437
943 : 1, 23, 41, 943
860 : 1, 2, 4, 5, 10, 20, 43, 86, 172, 215, 430, 860
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 991,362,437,943,860, is 1.
Now, the common factors can be found like this.
991:991
362:2x 181
437:19x 23
943:23x 41
860:2x 2x 5x 43
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 23 = 46
Therefore, the value for common factors is 46.
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 = 127137540588920/(1x46)
LCM = 127137540588920/46
LCM = 2763859578020
Thus, we can understand that the LCM of 991,362,437,943,860 is 2763859578020.
