The LCM of 609,689,624,693 is 221549328.
Find LCM of 609,689,624,693 with Prime Factorization
| 3 | 609, 689, 624, 693 |
| 7 | 203, 689, 208, 231 |
| 13 | 29, 689, 208, 33 |
| 29, 53, 16, 33 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 13 x 29 x 53 x 16 x 33 = 221549328
Therefore, the lowest common multiple of 609,689,624,693 is 221549328.
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.
609 x 689 x 624 x 693 = 181448899632
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.
609 : 1, 3, 7, 21, 29, 87, 203, 609
689 : 1, 13, 53, 689
624 : 1, 2, 3, 4, 6, 8, 12, 13, 16, 24, 26, 39, 48, 52, 78, 104, 156, 208, 312, 624
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 609,689,624,693, is 1.
Now, the common factors can be found like this.
609:3x 7x 29
689:13x 53
624:2x 2x 2x 2x 3x 13
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.
3x 3x 7x 13 = 819
Therefore, the value for common factors is 819.
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 = 181448899632/(1x819)
LCM = 181448899632/819
LCM = 221549328
Thus, we can understand that the LCM of 609,689,624,693 is 221549328.
