Find LCM of 853,754,870,897 with Prime Factorization
| 2 | 853, 754, 870, 897 |
| 3 | 853, 377, 435, 897 |
| 13 | 853, 377, 145, 299 |
| 29 | 853, 29, 145, 23 |
| 853, 1, 5, 23 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 13 x 29 x 853 x 1 x 5 x 23 = 221890890
Therefore, the lowest common multiple of 853,754,870,897 is 221890890.
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.
853 x 754 x 870 x 897 = 501917193180
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.
853 : 1, 853
754 : 1, 2, 13, 26, 29, 58, 377, 754
870 : 1, 2, 3, 5, 6, 10, 15, 29, 30, 58, 87, 145, 174, 290, 435, 870
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 853,754,870,897, is 1.
Now, the common factors can be found like this.
853:853
754:2x 13x 29
870:2x 3x 5x 29
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 3x 13x 29 = 2262
Therefore, the value for common factors is 2262.
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 = 501917193180/(1x2262)
LCM = 501917193180/2262
LCM = 221890890
Thus, we can understand that the LCM of 853,754,870,897 is 221890890.
