Given numbers are 799,187,371,689
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 799,187,371,689 is 42389347.
Find LCM of 799,187,371,689 with Prime Factorization
| 17 | 799, 187, 371, 689 |
| 53 | 47, 11, 371, 689 |
| 47, 11, 7, 13 |
Multiply the prime numbers at the bottom and the left side.
17 x 53 x 47 x 11 x 7 x 13 = 42389347
Therefore, the lowest common multiple of 799,187,371,689 is 42389347.
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.
799 x 187 x 371 x 689 = 38192801647
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.
799 : 1, 17, 47, 799
187 : 1, 11, 17, 187
371 : 1, 7, 53, 371
689 : 1, 13, 53, 689
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 799,187,371,689, is 1.
Now, the common factors can be found like this.
799:17x 47
187:11x 17
371:7x 53
689:13x 53
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
17x 53 = 901
Therefore, the value for common factors is 901.
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 = 38192801647/(1x901)
LCM = 38192801647/901
LCM = 42389347
Thus, we can understand that the LCM of 799,187,371,689 is 42389347.
