Find LCM of 616,795,901,972,645 with Prime Factorization
| 2 | 616, 795, 901, 972, 645 |
| 2 | 308, 795, 901, 486, 645 |
| 3 | 154, 795, 901, 243, 645 |
| 5 | 154, 265, 901, 81, 215 |
| 53 | 154, 53, 901, 81, 43 |
| 154, 1, 17, 81, 43 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 53 x 154 x 1 x 17 x 81 x 43 = 28996810920
Therefore, the lowest common multiple of 616,795,901,972,645 is 28996810920.
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.
616 x 795 x 901 x 972 x 645 = 276629576176800
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.
616 : 1, 2, 4, 7, 8, 11, 14, 22, 28, 44, 56, 77, 88, 154, 308, 616
795 : 1, 3, 5, 15, 53, 159, 265, 795
901 : 1, 17, 53, 901
972 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 243, 324, 486, 972
645 : 1, 3, 5, 15, 43, 129, 215, 645
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 616,795,901,972,645, is 1.
Now, the common factors can be found like this.
616:2x 2x 2x 7x 11
795:3x 5x 53
901:17x 53
972:2x 2x 3x 3x 3x 3x 3
645:3x 5x 43
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 3x 3x 5x 53 = 9540
Therefore, the value for common factors is 9540.
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 = 276629576176800/(1x9540)
LCM = 276629576176800/9540
LCM = 28996810920
Thus, we can understand that the LCM of 616,795,901,972,645 is 28996810920.
