Given numbers are 764,154,374,979,160
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 764,154,374,979,160 is 3560270560.
Find LCM of 764,154,374,979,160 with Prime Factorization
| 2 | 764, 154, 374, 979, 160 |
| 2 | 382, 77, 187, 979, 80 |
| 11 | 191, 77, 187, 979, 40 |
| 191, 7, 17, 89, 40 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 11 x 191 x 7 x 17 x 89 x 40 = 3560270560
Therefore, the lowest common multiple of 764,154,374,979,160 is 3560270560.
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.
764 x 154 x 374 x 979 x 160 = 6892683804160
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.
764 : 1, 2, 4, 191, 382, 764
154 : 1, 2, 7, 11, 14, 22, 77, 154
374 : 1, 2, 11, 17, 22, 34, 187, 374
979 : 1, 11, 89, 979
160 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 80, 160
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 764,154,374,979,160, is 1.
Now, the common factors can be found like this.
764:2x 2x 191
154:2x 7x 11
374:2x 11x 17
979:11x 89
160:2x 2x 2x 2x 2x 5
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 2x 11x 11 = 1936
Therefore, the value for common factors is 1936.
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 = 6892683804160/(1x1936)
LCM = 6892683804160/1936
LCM = 3560270560
Thus, we can understand that the LCM of 764,154,374,979,160 is 3560270560.
