Find LCM of 985,985,749,399,492 with Prime Factorization
| 3 | 985, 985, 749, 399, 492 |
| 5 | 985, 985, 749, 133, 164 |
| 7 | 197, 197, 749, 133, 164 |
| 197 | 197, 197, 107, 19, 164 |
| 1, 1, 107, 19, 164 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 7 x 197 x 1 x 1 x 107 x 19 x 164 = 6896627220
Therefore, the lowest common multiple of 985,985,749,399,492 is 6896627220.
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.
985 x 985 x 749 x 399 x 492 = 142656734045700
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.
985 : 1, 5, 197, 985
985 : 1, 5, 197, 985
749 : 1, 7, 107, 749
399 : 1, 3, 7, 19, 21, 57, 133, 399
492 : 1, 2, 3, 4, 6, 12, 41, 82, 123, 164, 246, 492
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 985,985,749,399,492, is 1.
Now, the common factors can be found like this.
985:5x 197
985:5x 197
749:7x 107
399:3x 7x 19
492:2x 2x 3x 41
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5x 7x 197 = 20685
Therefore, the value for common factors is 20685.
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 = 142656734045700/(1x20685)
LCM = 142656734045700/20685
LCM = 6896627220
Thus, we can understand that the LCM of 985,985,749,399,492 is 6896627220.
