Find LCM of 870,946,786,989,621 with Prime Factorization
2 | 870, 946, 786, 989, 621 |
3 | 435, 473, 393, 989, 621 |
23 | 145, 473, 131, 989, 207 |
43 | 145, 473, 131, 43, 9 |
145, 11, 131, 1, 9 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 23 x 43 x 145 x 11 x 131 x 1 x 9 = 11158916670
Therefore, the lowest common multiple of 870,946,786,989,621 is 11158916670.
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.
870 x 946 x 786 x 989 x 621 = 397302069118680
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.
870 : 1, 2, 3, 5, 6, 10, 15, 29, 30, 58, 87, 145, 174, 290, 435, 870
946 : 1, 2, 11, 22, 43, 86, 473, 946
786 : 1, 2, 3, 6, 131, 262, 393, 786
989 : 1, 23, 43, 989
621 : 1, 3, 9, 23, 27, 69, 207, 621
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 870,946,786,989,621, is 1.
Now, the common factors can be found like this.
870:2x 3x 5x 29
946:2x 11x 43
786:2x 3x 131
989:23x 43
621:3x 3x 3x 23
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 23x 43 = 35604
Therefore, the value for common factors is 35604.
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 = 397302069118680/(1x35604)
LCM = 397302069118680/35604
LCM = 11158916670
Thus, we can understand that the LCM of 870,946,786,989,621 is 11158916670.
