Find LCM of 770,645,578,835,720 with Prime Factorization
2 | 770, 645, 578, 835, 720 |
3 | 385, 645, 289, 835, 360 |
5 | 385, 215, 289, 835, 120 |
77, 43, 289, 167, 24 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 77 x 43 x 289 x 167 x 24 = 115055130960
Therefore, the lowest common multiple of 770,645,578,835,720 is 115055130960.
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.
770 x 645 x 578 x 835 x 720 = 172582696440000
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.
770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770
645 : 1, 3, 5, 15, 43, 129, 215, 645
578 : 1, 2, 17, 34, 289, 578
835 : 1, 5, 167, 835
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 770,645,578,835,720, is 1.
Now, the common factors can be found like this.
770:2x 5x 7x 11
645:3x 5x 43
578:2x 17x 17
835:5x 167
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 3x 5x 5x 5 = 1500
Therefore, the value for common factors is 1500.
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 = 172582696440000/(1x1500)
LCM = 172582696440000/1500
LCM = 115055130960
Thus, we can understand that the LCM of 770,645,578,835,720 is 115055130960.
