Find LCM of 845,130,689,154,693 with Prime Factorization
| 2 | 845, 130, 689, 154, 693 |
| 5 | 845, 65, 689, 77, 693 |
| 7 | 169, 13, 689, 77, 693 |
| 11 | 169, 13, 689, 11, 99 |
| 13 | 169, 13, 689, 1, 9 |
| 1, 13, 53, 1, 9 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 7 x 11 x 13 x 1 x 13 x 53 x 1 x 9 = 62072010
Therefore, the lowest common multiple of 845,130,689,154,693 is 62072010.
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.
845 x 130 x 689 x 154 x 693 = 8077430661300
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.
845 : 1, 5, 13, 65, 169, 845
130 : 1, 2, 5, 10, 13, 26, 65, 130
689 : 1, 13, 53, 689
154 : 1, 2, 7, 11, 14, 22, 77, 154
693 : 1, 3, 7, 9, 11, 21, 33, 63, 77, 99, 231, 693
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 845,130,689,154,693, is 1.
Now, the common factors can be found like this.
845:5x 13x 13
130:2x 5x 13
689:13x 53
154:2x 7x 11
693:3x 3x 7x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 7x 11x 13x 13 = 130130
Therefore, the value for common factors is 130130.
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 = 8077430661300/(1x130130)
LCM = 8077430661300/130130
LCM = 62072010
Thus, we can understand that the LCM of 845,130,689,154,693 is 62072010.
