Find LCM of 785,852,560,126 with Prime Factorization
| 2 | 785, 852, 560, 126 |
| 2 | 785, 426, 280, 63 |
| 3 | 785, 213, 140, 63 |
| 5 | 785, 71, 140, 21 |
| 7 | 157, 71, 28, 21 |
| 157, 71, 4, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 7 x 157 x 71 x 4 x 3 = 56180880
Therefore, the lowest common multiple of 785,852,560,126 is 56180880.
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.
785 x 852 x 560 x 126 = 47191939200
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.
785 : 1, 5, 157, 785
852 : 1, 2, 3, 4, 6, 12, 71, 142, 213, 284, 426, 852
560 : 1, 2, 4, 5, 7, 8, 10, 14, 16, 20, 28, 35, 40, 56, 70, 80, 112, 140, 280, 560
126 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 42, 63, 126
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 785,852,560,126, is 1.
Now, the common factors can be found like this.
785:5x 157
852:2x 2x 3x 71
560:2x 2x 2x 2x 5x 7
126:2x 3x 3x 7
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 5x 7 = 840
Therefore, the value for common factors is 840.
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 = 47191939200/(1x840)
LCM = 47191939200/840
LCM = 56180880
Thus, we can understand that the LCM of 785,852,560,126 is 56180880.
