Find LCM of 720,492,644,851,246 with Prime Factorization
| 2 | 720, 492, 644, 851, 246 |
| 2 | 360, 246, 322, 851, 123 |
| 3 | 180, 123, 161, 851, 123 |
| 23 | 60, 41, 161, 851, 41 |
| 41 | 60, 41, 7, 37, 41 |
| 60, 1, 7, 37, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 23 x 41 x 60 x 1 x 7 x 37 x 1 = 175850640
Therefore, the lowest common multiple of 720,492,644,851,246 is 175850640.
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.
720 x 492 x 644 x 851 x 246 = 47758220213760
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.
720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720
492 : 1, 2, 3, 4, 6, 12, 41, 82, 123, 164, 246, 492
644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644
851 : 1, 23, 37, 851
246 : 1, 2, 3, 6, 41, 82, 123, 246
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 720,492,644,851,246, is 1.
Now, the common factors can be found like this.
720:2x 2x 2x 2x 3x 3x 5
492:2x 2x 3x 41
644:2x 2x 7x 23
851:23x 37
246:2x 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.
2x 2x 2x 2x 2x 3x 3x 23x 41 = 271584
Therefore, the value for common factors is 271584.
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 = 47758220213760/(1x271584)
LCM = 47758220213760/271584
LCM = 175850640
Thus, we can understand that the LCM of 720,492,644,851,246 is 175850640.
