The LCM of 578,170,798,685,635 is 20062960890.
Find LCM of 578,170,798,685,635 with Prime Factorization
| 2 | 578, 170, 798, 685, 635 |
| 5 | 289, 85, 399, 685, 635 |
| 17 | 289, 17, 399, 137, 127 |
| 1, 17, 399, 137, 127 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 17 x 1 x 17 x 399 x 137 x 127 = 20062960890
Therefore, the lowest common multiple of 578,170,798,685,635 is 20062960890.
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 170 x 798 x 685 x 635 = 34107033513000
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
170 : 1, 2, 5, 10, 17, 34, 85, 170
798 : 1, 2, 3, 6, 7, 14, 19, 21, 38, 42, 57, 114, 133, 266, 399, 798
685 : 1, 5, 137, 685
635 : 1, 5, 127, 635
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 578,170,798,685,635, is 1.
Now, the common factors can be found like this.
578:2x 17x 17
170:2x 5x 17
798:2x 3x 7x 19
685:5x 137
635:5x 127
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 5x 5x 17 = 1700
Therefore, the value for common factors is 1700.
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 = 34107033513000/(1x1700)
LCM = 34107033513000/1700
LCM = 20062960890
Thus, we can understand that the LCM of 578,170,798,685,635 is 20062960890.
