Given numbers are 774,784,136,520,794
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 774,784,136,520,794 is 133100538480.
Find LCM of 774,784,136,520,794 with Prime Factorization
| 2 | 774, 784, 136, 520, 794 |
| 2 | 387, 392, 68, 260, 397 |
| 2 | 387, 196, 34, 130, 397 |
| 387, 98, 17, 65, 397 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 387 x 98 x 17 x 65 x 397 = 133100538480
Therefore, the lowest common multiple of 774,784,136,520,794 is 133100538480.
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.
774 x 784 x 136 x 520 x 794 = 34073737850880
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.
774 : 1, 2, 3, 6, 9, 18, 43, 86, 129, 258, 387, 774
784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784
136 : 1, 2, 4, 8, 17, 34, 68, 136
520 : 1, 2, 4, 5, 8, 10, 13, 20, 26, 40, 52, 65, 104, 130, 260, 520
794 : 1, 2, 397, 794
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 774,784,136,520,794, is 2.
Now, the common factors can be found like this.
774:2x 3x 3x 43
784:2x 2x 2x 2x 7x 7
136:2x 2x 2x 17
520:2x 2x 2x 5x 13
794:2x 397
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 2x 2x 2 = 128
Therefore, the value for common factors is 128.
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 = 34073737850880/(2x128)
LCM = 34073737850880/256
LCM = 133100538480
Thus, we can understand that the LCM of 774,784,136,520,794 is 133100538480.
