Find LCM of 975,790,708,899,643 with Prime Factorization
| 2 | 975, 790, 708, 899, 643 |
| 3 | 975, 395, 354, 899, 643 |
| 5 | 325, 395, 118, 899, 643 |
| 65, 79, 118, 899, 643 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 65 x 79 x 118 x 899 x 643 = 10507862340300
Therefore, the lowest common multiple of 975,790,708,899,643 is 10507862340300.
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.
975 x 790 x 708 x 899 x 643 = 315235870209000
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.
975 : 1, 3, 5, 13, 15, 25, 39, 65, 75, 195, 325, 975
790 : 1, 2, 5, 10, 79, 158, 395, 790
708 : 1, 2, 3, 4, 6, 12, 59, 118, 177, 236, 354, 708
899 : 1, 29, 31, 899
643 : 1, 643
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 975,790,708,899,643, is 1.
Now, the common factors can be found like this.
975:3x 5x 5x 13
790:2x 5x 79
708:2x 2x 3x 59
899:29x 31
643:643
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 5 = 30
Therefore, the value for common factors is 30.
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 = 315235870209000/(1x30)
LCM = 315235870209000/30
LCM = 10507862340300
Thus, we can understand that the LCM of 975,790,708,899,643 is 10507862340300.
