Find LCM of 738,678,846,178,987 with Prime Factorization
2 | 738, 678, 846, 178, 987 |
3 | 369, 339, 423, 89, 987 |
3 | 123, 113, 141, 89, 329 |
47 | 41, 113, 47, 89, 329 |
41, 113, 1, 89, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 47 x 41 x 113 x 1 x 89 x 7 = 2441859714
Therefore, the lowest common multiple of 738,678,846,178,987 is 2441859714.
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.
738 x 678 x 846 x 178 x 987 = 74369279449584
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.
738 : 1, 2, 3, 6, 9, 18, 41, 82, 123, 246, 369, 738
678 : 1, 2, 3, 6, 113, 226, 339, 678
846 : 1, 2, 3, 6, 9, 18, 47, 94, 141, 282, 423, 846
178 : 1, 2, 89, 178
987 : 1, 3, 7, 21, 47, 141, 329, 987
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 738,678,846,178,987, is 1.
Now, the common factors can be found like this.
738:2x 3x 3x 41
678:2x 3x 113
846:2x 3x 3x 47
178:2x 89
987:3x 7x 47
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 3x 3x 3x 47 = 30456
Therefore, the value for common factors is 30456.
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 = 74369279449584/(1x30456)
LCM = 74369279449584/30456
LCM = 2441859714
Thus, we can understand that the LCM of 738,678,846,178,987 is 2441859714.
