Find LCM of 916,724,911,210,135 with Prime Factorization
| 2 | 916, 724, 911, 210, 135 |
| 2 | 458, 362, 911, 105, 135 |
| 3 | 229, 181, 911, 105, 135 |
| 5 | 229, 181, 911, 35, 45 |
| 229, 181, 911, 7, 9 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 229 x 181 x 911 x 7 x 9 = 142732947420
Therefore, the lowest common multiple of 916,724,911,210,135 is 142732947420.
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.
916 x 724 x 911 x 210 x 135 = 17127953690400
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.
916 : 1, 2, 4, 229, 458, 916
724 : 1, 2, 4, 181, 362, 724
911 : 1, 911
210 : 1, 2, 3, 5, 6, 7, 10, 14, 15, 21, 30, 35, 42, 70, 105, 210
135 : 1, 3, 5, 9, 15, 27, 45, 135
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 916,724,911,210,135, is 1.
Now, the common factors can be found like this.
916:2x 2x 229
724:2x 2x 181
911:911
210:2x 3x 5x 7
135:3x 3x 3x 5
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 5 = 120
Therefore, the value for common factors is 120.
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 = 17127953690400/(1x120)
LCM = 17127953690400/120
LCM = 142732947420
Thus, we can understand that the LCM of 916,724,911,210,135 is 142732947420.
