The LCM of 917,756,652,531 is 952429212.
Find LCM of 917,756,652,531 with Prime Factorization
| 2 | 917, 756, 652, 531 |
| 2 | 917, 378, 326, 531 |
| 3 | 917, 189, 163, 531 |
| 3 | 917, 63, 163, 177 |
| 7 | 917, 21, 163, 59 |
| 131, 3, 163, 59 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 7 x 131 x 3 x 163 x 59 = 952429212
Therefore, the lowest common multiple of 917,756,652,531 is 952429212.
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.
917 x 756 x 652 x 531 = 240012161424
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.
917 : 1, 7, 131, 917
756 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 27, 28, 36, 42, 54, 63, 84, 108, 126, 189, 252, 378, 756
652 : 1, 2, 4, 163, 326, 652
531 : 1, 3, 9, 59, 177, 531
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 917,756,652,531, is 1.
Now, the common factors can be found like this.
917:7x 131
756:2x 2x 3x 3x 3x 7
652:2x 2x 163
531:3x 3x 59
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 3x 3x 7 = 252
Therefore, the value for common factors is 252.
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 = 240012161424/(1x252)
LCM = 240012161424/252
LCM = 952429212
Thus, we can understand that the LCM of 917,756,652,531 is 952429212.
