Find LCM of 798,621,767,931,485 with Prime Factorization
| 3 | 798, 621, 767, 931, 485 |
| 7 | 266, 207, 767, 931, 485 |
| 19 | 38, 207, 767, 133, 485 |
| 2, 207, 767, 7, 485 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 19 x 2 x 207 x 767 x 7 x 485 = 430138562490
Therefore, the lowest common multiple of 798,621,767,931,485 is 430138562490.
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.
798 x 621 x 767 x 931 x 485 = 171625286433510
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.
798 : 1, 2, 3, 6, 7, 14, 19, 21, 38, 42, 57, 114, 133, 266, 399, 798
621 : 1, 3, 9, 23, 27, 69, 207, 621
767 : 1, 13, 59, 767
931 : 1, 7, 19, 49, 133, 931
485 : 1, 5, 97, 485
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 798,621,767,931,485, is 1.
Now, the common factors can be found like this.
798:2x 3x 7x 19
621:3x 3x 3x 23
767:13x 59
931:7x 7x 19
485:5x 97
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 7x 19 = 399
Therefore, the value for common factors is 399.
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 = 171625286433510/(1x399)
LCM = 171625286433510/399
LCM = 430138562490
Thus, we can understand that the LCM of 798,621,767,931,485 is 430138562490.
