Find LCM of 847,357,236,663,689 with Prime Factorization
3 | 847, 357, 236, 663, 689 |
7 | 847, 119, 236, 221, 689 |
13 | 121, 17, 236, 221, 689 |
17 | 121, 17, 236, 17, 53 |
121, 1, 236, 1, 53 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 13 x 17 x 121 x 1 x 236 x 1 x 53 = 7024004988
Therefore, the lowest common multiple of 847,357,236,663,689 is 7024004988.
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.
847 x 357 x 236 x 663 x 689 = 32598407149308
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.
847 : 1, 7, 11, 77, 121, 847
357 : 1, 3, 7, 17, 21, 51, 119, 357
236 : 1, 2, 4, 59, 118, 236
663 : 1, 3, 13, 17, 39, 51, 221, 663
689 : 1, 13, 53, 689
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 847,357,236,663,689, is 1.
Now, the common factors can be found like this.
847:7x 11x 11
357:3x 7x 17
236:2x 2x 59
663:3x 13x 17
689:13x 53
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 7x 13x 17 = 4641
Therefore, the value for common factors is 4641.
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 = 32598407149308/(1x4641)
LCM = 32598407149308/4641
LCM = 7024004988
Thus, we can understand that the LCM of 847,357,236,663,689 is 7024004988.
