Find LCM of 973,663,816,720 with Prime Factorization
2 | 973, 663, 816, 720 |
2 | 973, 663, 408, 360 |
2 | 973, 663, 204, 180 |
2 | 973, 663, 102, 90 |
3 | 973, 663, 51, 45 |
17 | 973, 221, 17, 15 |
973, 13, 1, 15 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 17 x 973 x 13 x 1 x 15 = 154823760
Therefore, the lowest common multiple of 973,663,816,720 is 154823760.
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.
973 x 663 x 816 x 720 = 379008564480
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.
973 : 1, 7, 139, 973
663 : 1, 3, 13, 17, 39, 51, 221, 663
816 : 1, 2, 3, 4, 6, 8, 12, 16, 17, 24, 34, 48, 51, 68, 102, 136, 204, 272, 408, 816
720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 973,663,816,720, is 1.
Now, the common factors can be found like this.
973:7x 139
663:3x 13x 17
816:2x 2x 2x 2x 3x 17
720:2x 2x 2x 2x 3x 3x 5
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 3x 17 = 2448
Therefore, the value for common factors is 2448.
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 = 379008564480/(1x2448)
LCM = 379008564480/2448
LCM = 154823760
Thus, we can understand that the LCM of 973,663,816,720 is 154823760.
