The LCM of 783,540,653,621,705 is 11054284380.
Find LCM of 783,540,653,621,705 with Prime Factorization
| 3 | 783, 540, 653, 621, 705 |
| 3 | 261, 180, 653, 207, 235 |
| 3 | 87, 60, 653, 69, 235 |
| 5 | 29, 20, 653, 23, 235 |
| 29, 4, 653, 23, 47 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 3 x 5 x 29 x 4 x 653 x 23 x 47 = 11054284380
Therefore, the lowest common multiple of 783,540,653,621,705 is 11054284380.
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.
783 x 540 x 653 x 621 x 705 = 120878599695300
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.
783 : 1, 3, 9, 27, 29, 87, 261, 783
540 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 27, 30, 36, 45, 54, 60, 90, 108, 135, 180, 270, 540
653 : 1, 653
621 : 1, 3, 9, 23, 27, 69, 207, 621
705 : 1, 3, 5, 15, 47, 141, 235, 705
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 783,540,653,621,705, is 1.
Now, the common factors can be found like this.
783:3x 3x 3x 29
540:2x 2x 3x 3x 3x 5
653:653
621:3x 3x 3x 23
705:3x 5x 47
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 3x 3x 3x 3x 3x 5 = 10935
Therefore, the value for common factors is 10935.
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 = 120878599695300/(1x10935)
LCM = 120878599695300/10935
LCM = 11054284380
Thus, we can understand that the LCM of 783,540,653,621,705 is 11054284380.
