Find LCM of 438,688,819,364 with Prime Factorization
2 | 438, 688, 819, 364 |
2 | 219, 344, 819, 182 |
3 | 219, 172, 819, 91 |
7 | 73, 172, 273, 91 |
13 | 73, 172, 39, 13 |
73, 172, 3, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 13 x 73 x 172 x 3 x 1 = 41133456
Therefore, the lowest common multiple of 438,688,819,364 is 41133456.
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.
438 x 688 x 819 x 364 = 89835467904
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.
438 : 1, 2, 3, 6, 73, 146, 219, 438
688 : 1, 2, 4, 8, 16, 43, 86, 172, 344, 688
819 : 1, 3, 7, 9, 13, 21, 39, 63, 91, 117, 273, 819
364 : 1, 2, 4, 7, 13, 14, 26, 28, 52, 91, 182, 364
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 438,688,819,364, is 1.
Now, the common factors can be found like this.
438:2x 3x 73
688:2x 2x 2x 2x 43
819:3x 3x 7x 13
364:2x 2x 7x 13
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 2x 3x 7x 13 = 2184
Therefore, the value for common factors is 2184.
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 = 89835467904/(1x2184)
LCM = 89835467904/2184
LCM = 41133456
Thus, we can understand that the LCM of 438,688,819,364 is 41133456.
