The LCM of 702,494,897,821 is 251861454.
Find LCM of 702,494,897,821 with Prime Factorization
2 | 702, 494, 897, 821 |
3 | 351, 247, 897, 821 |
13 | 117, 247, 299, 821 |
9, 19, 23, 821 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 13 x 9 x 19 x 23 x 821 = 251861454
Therefore, the lowest common multiple of 702,494,897,821 is 251861454.
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.
702 x 494 x 897 x 821 = 255387514356
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.
702 : 1, 2, 3, 6, 9, 13, 18, 26, 27, 39, 54, 78, 117, 234, 351, 702
494 : 1, 2, 13, 19, 26, 38, 247, 494
897 : 1, 3, 13, 23, 39, 69, 299, 897
821 : 1, 821
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 702,494,897,821, is 1.
Now, the common factors can be found like this.
702:2x 3x 3x 3x 13
494:2x 13x 19
897:3x 13x 23
821:821
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 13 = 1014
Therefore, the value for common factors is 1014.
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 = 255387514356/(1x1014)
LCM = 255387514356/1014
LCM = 251861454
Thus, we can understand that the LCM of 702,494,897,821 is 251861454.
