The LCM of 492,784,851,897 is 1066827216.
Find LCM of 492,784,851,897 with Prime Factorization
| 2 | 492, 784, 851, 897 |
| 2 | 246, 392, 851, 897 |
| 3 | 123, 196, 851, 897 |
| 23 | 41, 196, 851, 299 |
| 41, 196, 37, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 23 x 41 x 196 x 37 x 13 = 1066827216
Therefore, the lowest common multiple of 492,784,851,897 is 1066827216.
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.
492 x 784 x 851 x 897 = 294444311616
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.
492 : 1, 2, 3, 4, 6, 12, 41, 82, 123, 164, 246, 492
784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784
851 : 1, 23, 37, 851
897 : 1, 3, 13, 23, 39, 69, 299, 897
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 492,784,851,897, is 1.
Now, the common factors can be found like this.
492:2x 2x 3x 41
784:2x 2x 2x 2x 7x 7
851:23x 37
897:3x 13x 23
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 3x 23 = 276
Therefore, the value for common factors is 276.
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 = 294444311616/(1x276)
LCM = 294444311616/276
LCM = 1066827216
Thus, we can understand that the LCM of 492,784,851,897 is 1066827216.
