Find LCM of 644,246,740,635,834 with Prime Factorization
2 | 644, 246, 740, 635, 834 |
2 | 322, 123, 370, 635, 417 |
3 | 161, 123, 185, 635, 417 |
5 | 161, 41, 185, 635, 139 |
161, 41, 37, 127, 139 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 161 x 41 x 37 x 127 x 139 = 258690945660
Therefore, the lowest common multiple of 644,246,740,635,834 is 258690945660.
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.
644 x 246 x 740 x 635 x 834 = 62085826958400
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.
644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644
246 : 1, 2, 3, 6, 41, 82, 123, 246
740 : 1, 2, 4, 5, 10, 20, 37, 74, 148, 185, 370, 740
635 : 1, 5, 127, 635
834 : 1, 2, 3, 6, 139, 278, 417, 834
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 644,246,740,635,834, is 1.
Now, the common factors can be found like this.
644:2x 2x 7x 23
246:2x 3x 41
740:2x 2x 5x 37
635:5x 127
834:2x 3x 139
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 2x 3x 5 = 240
Therefore, the value for common factors is 240.
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 = 62085826958400/(1x240)
LCM = 62085826958400/240
LCM = 258690945660
Thus, we can understand that the LCM of 644,246,740,635,834 is 258690945660.
