Given numbers are 778,754,744,959,171
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 778,754,744,959,171 is 5964270746616.
Find LCM of 778,754,744,959,171 with Prime Factorization
| 2 | 778, 754, 744, 959, 171 |
| 3 | 389, 377, 372, 959, 171 |
| 389, 377, 124, 959, 57 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 389 x 377 x 124 x 959 x 57 = 5964270746616
Therefore, the lowest common multiple of 778,754,744,959,171 is 5964270746616.
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 754 x 744 x 959 x 171 = 71571248959392
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
754 : 1, 2, 13, 26, 29, 58, 377, 754
744 : 1, 2, 3, 4, 6, 8, 12, 24, 31, 62, 93, 124, 186, 248, 372, 744
959 : 1, 7, 137, 959
171 : 1, 3, 9, 19, 57, 171
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 778,754,744,959,171, is 1.
Now, the common factors can be found like this.
778:2x 389
754:2x 13x 29
744:2x 2x 2x 3x 31
959:7x 137
171:3x 3x 19
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 = 71571248959392/(1x12)
LCM = 71571248959392/12
LCM = 5964270746616
Thus, we can understand that the LCM of 778,754,744,959,171 is 5964270746616.
