Find LCM of 578,784,961,952 with Prime Factorization
| 2 | 578, 784, 961, 952 |
| 2 | 289, 392, 961, 476 |
| 2 | 289, 196, 961, 238 |
| 7 | 289, 98, 961, 119 |
| 17 | 289, 14, 961, 17 |
| 1, 14, 961, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 7 x 17 x 1 x 14 x 961 x 17 = 217739536
Therefore, the lowest common multiple of 578,784,961,952 is 217739536.
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 784 x 961 x 952 = 414576076544
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
784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784
961 : 1, 31, 961
952 : 1, 2, 4, 7, 8, 14, 17, 28, 34, 56, 68, 119, 136, 238, 476, 952
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 578,784,961,952, is 1.
Now, the common factors can be found like this.
578:2x 17x 17
784:2x 2x 2x 2x 7x 7
961:31x 31
952:2x 2x 2x 7x 17
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 7x 17 = 1904
Therefore, the value for common factors is 1904.
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 = 414576076544/(1x1904)
LCM = 414576076544/1904
LCM = 217739536
Thus, we can understand that the LCM of 578,784,961,952 is 217739536.
