The LCM of 897,420,948,851 is 367070340.
Find LCM of 897,420,948,851 with Prime Factorization
2 | 897, 420, 948, 851 |
2 | 897, 210, 474, 851 |
3 | 897, 105, 237, 851 |
23 | 299, 35, 79, 851 |
13, 35, 79, 37 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 23 x 13 x 35 x 79 x 37 = 367070340
Therefore, the lowest common multiple of 897,420,948,851 is 367070340.
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.
897 x 420 x 948 x 851 = 303934241520
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.
897 : 1, 3, 13, 23, 39, 69, 299, 897
420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420
948 : 1, 2, 3, 4, 6, 12, 79, 158, 237, 316, 474, 948
851 : 1, 23, 37, 851
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 897,420,948,851, is 1.
Now, the common factors can be found like this.
897:3x 13x 23
420:2x 2x 3x 5x 7
948:2x 2x 3x 79
851:23x 37
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 3x 23 = 828
Therefore, the value for common factors is 828.
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 = 303934241520/(1x828)
LCM = 303934241520/828
LCM = 367070340
Thus, we can understand that the LCM of 897,420,948,851 is 367070340.
