The LCM of 766,661,800,702,420 is 497617192800.
Find LCM of 766,661,800,702,420 with Prime Factorization
| 2 | 766, 661, 800, 702, 420 |
| 2 | 383, 661, 400, 351, 210 |
| 3 | 383, 661, 200, 351, 105 |
| 5 | 383, 661, 200, 117, 35 |
| 383, 661, 40, 117, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 383 x 661 x 40 x 117 x 7 = 497617192800
Therefore, the lowest common multiple of 766,661,800,702,420 is 497617192800.
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.
766 x 661 x 800 x 702 x 420 = 119428126272000
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.
766 : 1, 2, 383, 766
661 : 1, 661
800 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 32, 40, 50, 80, 100, 160, 200, 400, 800
702 : 1, 2, 3, 6, 9, 13, 18, 26, 27, 39, 54, 78, 117, 234, 351, 702
420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 766,661,800,702,420, is 1.
Now, the common factors can be found like this.
766:2x 383
661:661
800:2x 2x 2x 2x 2x 5x 5
702:2x 3x 3x 3x 13
420:2x 2x 3x 5x 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 2x 3x 5 = 240
Therefore, the value for common factors is 240.
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 = 119428126272000/(1x240)
LCM = 119428126272000/240
LCM = 497617192800
Thus, we can understand that the LCM of 766,661,800,702,420 is 497617192800.
