Find LCM of 621,686,968,495,713 with Prime Factorization
| 2 | 621, 686, 968, 495, 713 |
| 3 | 621, 343, 484, 495, 713 |
| 3 | 207, 343, 484, 165, 713 |
| 11 | 69, 343, 484, 55, 713 |
| 23 | 69, 343, 44, 5, 713 |
| 3, 343, 44, 5, 31 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 11 x 23 x 3 x 343 x 44 x 5 x 31 = 31958970120
Therefore, the lowest common multiple of 621,686,968,495,713 is 31958970120.
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.
621 x 686 x 968 x 495 x 713 = 145541149926480
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.
621 : 1, 3, 9, 23, 27, 69, 207, 621
686 : 1, 2, 7, 14, 49, 98, 343, 686
968 : 1, 2, 4, 8, 11, 22, 44, 88, 121, 242, 484, 968
495 : 1, 3, 5, 9, 11, 15, 33, 45, 55, 99, 165, 495
713 : 1, 23, 31, 713
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 621,686,968,495,713, is 1.
Now, the common factors can be found like this.
621:3x 3x 3x 23
686:2x 7x 7x 7
968:2x 2x 2x 11x 11
495:3x 3x 5x 11
713:23x 31
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 11x 23 = 4554
Therefore, the value for common factors is 4554.
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 = 145541149926480/(1x4554)
LCM = 145541149926480/4554
LCM = 31958970120
Thus, we can understand that the LCM of 621,686,968,495,713 is 31958970120.
