Given numbers are 778,948,172,943,986
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 778,948,172,943,986 is 7371994563204.
Find LCM of 778,948,172,943,986 with Prime Factorization
| 2 | 778, 948, 172, 943, 986 |
| 2 | 389, 474, 86, 943, 493 |
| 389, 237, 43, 943, 493 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 389 x 237 x 43 x 943 x 493 = 7371994563204
Therefore, the lowest common multiple of 778,948,172,943,986 is 7371994563204.
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.
778 x 948 x 172 x 943 x 986 = 117951913011264
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.
778 : 1, 2, 389, 778
948 : 1, 2, 3, 4, 6, 12, 79, 158, 237, 316, 474, 948
172 : 1, 2, 4, 43, 86, 172
943 : 1, 23, 41, 943
986 : 1, 2, 17, 29, 34, 58, 493, 986
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 778,948,172,943,986, is 1.
Now, the common factors can be found like this.
778:2x 389
948:2x 2x 3x 79
172:2x 2x 43
943:23x 41
986:2x 17x 29
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 2x 2 = 16
Therefore, the value for common factors is 16.
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 = 117951913011264/(1x16)
LCM = 117951913011264/16
LCM = 7371994563204
Thus, we can understand that the LCM of 778,948,172,943,986 is 7371994563204.
