Find LCM of 712,972,806,490,765 with Prime Factorization
2 | 712, 972, 806, 490, 765 |
2 | 356, 486, 403, 245, 765 |
3 | 178, 243, 403, 245, 765 |
3 | 178, 81, 403, 245, 255 |
5 | 178, 27, 403, 245, 85 |
178, 27, 403, 49, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 5 x 178 x 27 x 403 x 49 x 17 = 290406490920
Therefore, the lowest common multiple of 712,972,806,490,765 is 290406490920.
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.
712 x 972 x 806 x 490 x 765 = 209092673462400
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.
712 : 1, 2, 4, 8, 89, 178, 356, 712
972 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 243, 324, 486, 972
806 : 1, 2, 13, 26, 31, 62, 403, 806
490 : 1, 2, 5, 7, 10, 14, 35, 49, 70, 98, 245, 490
765 : 1, 3, 5, 9, 15, 17, 45, 51, 85, 153, 255, 765
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 712,972,806,490,765, is 1.
Now, the common factors can be found like this.
712:2x 2x 2x 89
972:2x 2x 3x 3x 3x 3x 3
806:2x 13x 31
490:2x 5x 7x 7
765:3x 3x 5x 17
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 3x 3x 5 = 720
Therefore, the value for common factors is 720.
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 = 209092673462400/(1x720)
LCM = 209092673462400/720
LCM = 290406490920
Thus, we can understand that the LCM of 712,972,806,490,765 is 290406490920.
