Find LCM of 628,806,436,969,782 with Prime Factorization
2 | 628, 806, 436, 969, 782 |
2 | 314, 403, 218, 969, 391 |
17 | 157, 403, 109, 969, 391 |
157, 403, 109, 57, 23 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 17 x 157 x 403 x 109 x 57 x 23 = 614812658772
Therefore, the lowest common multiple of 628,806,436,969,782 is 614812658772.
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.
628 x 806 x 436 x 969 x 782 = 167229043185984
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.
628 : 1, 2, 4, 157, 314, 628
806 : 1, 2, 13, 26, 31, 62, 403, 806
436 : 1, 2, 4, 109, 218, 436
969 : 1, 3, 17, 19, 51, 57, 323, 969
782 : 1, 2, 17, 23, 34, 46, 391, 782
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 628,806,436,969,782, is 1.
Now, the common factors can be found like this.
628:2x 2x 157
806:2x 13x 31
436:2x 2x 109
969:3x 17x 19
782:2x 17x 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 2x 2x 17 = 272
Therefore, the value for common factors is 272.
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 = 167229043185984/(1x272)
LCM = 167229043185984/272
LCM = 614812658772
Thus, we can understand that the LCM of 628,806,436,969,782 is 614812658772.
