Given numbers are 974,861,871,724,724
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 974,861,871,724,724 is 264416671428.
Find LCM of 974,861,871,724,724 with Prime Factorization
| 2 | 974, 861, 871, 724, 724 |
| 2 | 487, 861, 871, 362, 362 |
| 181 | 487, 861, 871, 181, 181 |
| 487, 861, 871, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 181 x 487 x 861 x 871 x 1 x 1 = 264416671428
Therefore, the lowest common multiple of 974,861,871,724,724 is 264416671428.
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.
974 x 861 x 871 x 724 x 724 = 382875340227744
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.
974 : 1, 2, 487, 974
861 : 1, 3, 7, 21, 41, 123, 287, 861
871 : 1, 13, 67, 871
724 : 1, 2, 4, 181, 362, 724
724 : 1, 2, 4, 181, 362, 724
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 974,861,871,724,724, is 1.
Now, the common factors can be found like this.
974:2x 487
861:3x 7x 41
871:13x 67
724:2x 2x 181
724:2x 2x 181
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 181 = 1448
Therefore, the value for common factors is 1448.
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 = 382875340227744/(1x1448)
LCM = 382875340227744/1448
LCM = 264416671428
Thus, we can understand that the LCM of 974,861,871,724,724 is 264416671428.
