Find LCM of 791,560,585,821,988 with Prime Factorization
2 | 791, 560, 585, 821, 988 |
2 | 791, 280, 585, 821, 494 |
5 | 791, 140, 585, 821, 247 |
7 | 791, 28, 117, 821, 247 |
13 | 113, 4, 117, 821, 247 |
113, 4, 9, 821, 19 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 7 x 13 x 113 x 4 x 9 x 821 x 19 = 115491252240
Therefore, the lowest common multiple of 791,560,585,821,988 is 115491252240.
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.
791 x 560 x 585 x 821 x 988 = 210194079076800
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.
791 : 1, 7, 113, 791
560 : 1, 2, 4, 5, 7, 8, 10, 14, 16, 20, 28, 35, 40, 56, 70, 80, 112, 140, 280, 560
585 : 1, 3, 5, 9, 13, 15, 39, 45, 65, 117, 195, 585
821 : 1, 821
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 791,560,585,821,988, is 1.
Now, the common factors can be found like this.
791:7x 113
560:2x 2x 2x 2x 5x 7
585:3x 3x 5x 13
821:821
988:2x 2x 13x 19
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 5x 7x 13 = 1820
Therefore, the value for common factors is 1820.
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 = 210194079076800/(1x1820)
LCM = 210194079076800/1820
LCM = 115491252240
Thus, we can understand that the LCM of 791,560,585,821,988 is 115491252240.
