Find LCM of 738,657,449,766,990 with Prime Factorization
2 | 738, 657, 449, 766, 990 |
3 | 369, 657, 449, 383, 495 |
3 | 123, 219, 449, 383, 165 |
41, 73, 449, 383, 55 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 41 x 73 x 449 x 383 x 55 = 509550258690
Therefore, the lowest common multiple of 738,657,449,766,990 is 509550258690.
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 657 x 449 x 766 x 990 = 165094283815560
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
657 : 1, 3, 9, 73, 219, 657
449 : 1, 449
766 : 1, 2, 383, 766
990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 738,657,449,766,990, is 1.
Now, the common factors can be found like this.
738:2x 3x 3x 41
657:3x 3x 73
449:449
766:2x 383
990:2x 3x 3x 5x 11
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 3x 3 = 324
Therefore, the value for common factors is 324.
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 = 165094283815560/(1x324)
LCM = 165094283815560/324
LCM = 509550258690
Thus, we can understand that the LCM of 738,657,449,766,990 is 509550258690.
