Given numbers are 578,869,605,969
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 578,869,605,969 is 1574654070.
Find LCM of 578,869,605,969 with Prime Factorization
| 11 | 578, 869, 605, 969 |
| 17 | 578, 79, 55, 969 |
| 34, 79, 55, 57 |
Multiply the prime numbers at the bottom and the left side.
11 x 17 x 34 x 79 x 55 x 57 = 1574654070
Therefore, the lowest common multiple of 578,869,605,969 is 1574654070.
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.
578 x 869 x 605 x 969 = 294460311090
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.
578 : 1, 2, 17, 34, 289, 578
869 : 1, 11, 79, 869
605 : 1, 5, 11, 55, 121, 605
969 : 1, 3, 17, 19, 51, 57, 323, 969
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 578,869,605,969, is 1.
Now, the common factors can be found like this.
578:2x 17x 17
869:11x 79
605:5x 11x 11
969:3x 17x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
11x 17 = 187
Therefore, the value for common factors is 187.
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 = 294460311090/(1x187)
LCM = 294460311090/187
LCM = 1574654070
Thus, we can understand that the LCM of 578,869,605,969 is 1574654070.
