Given numbers are 784,663,871,603
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 784,663,871,603 is 104478192.
Find LCM of 784,663,871,603 with Prime Factorization
| 3 | 784, 663, 871, 603 |
| 13 | 784, 221, 871, 201 |
| 67 | 784, 17, 67, 201 |
| 784, 17, 1, 3 |
Multiply the prime numbers at the bottom and the left side.
3 x 13 x 67 x 784 x 17 x 1 x 3 = 104478192
Therefore, the lowest common multiple of 784,663,871,603 is 104478192.
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.
784 x 663 x 871 x 603 = 273001515696
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.
784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784
663 : 1, 3, 13, 17, 39, 51, 221, 663
871 : 1, 13, 67, 871
603 : 1, 3, 9, 67, 201, 603
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 784,663,871,603, is 1.
Now, the common factors can be found like this.
784:2x 2x 2x 2x 7x 7
663:3x 13x 17
871:13x 67
603:3x 3x 67
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 13x 67 = 2613
Therefore, the value for common factors is 2613.
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 = 273001515696/(1x2613)
LCM = 273001515696/2613
LCM = 104478192
Thus, we can understand that the LCM of 784,663,871,603 is 104478192.
