Find LCM of 195,174,689,638,684 with Prime Factorization
| 2 | 195, 174, 689, 638, 684 |
| 3 | 195, 87, 689, 319, 342 |
| 13 | 65, 29, 689, 319, 114 |
| 29 | 5, 29, 53, 319, 114 |
| 5, 1, 53, 11, 114 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 13 x 29 x 5 x 1 x 53 x 11 x 114 = 751685220
Therefore, the lowest common multiple of 195,174,689,638,684 is 751685220.
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.
195 x 174 x 689 x 638 x 684 = 10201871805840
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.
195 : 1, 3, 5, 13, 15, 39, 65, 195
174 : 1, 2, 3, 6, 29, 58, 87, 174
689 : 1, 13, 53, 689
638 : 1, 2, 11, 22, 29, 58, 319, 638
684 : 1, 2, 3, 4, 6, 9, 12, 18, 19, 36, 38, 57, 76, 114, 171, 228, 342, 684
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 195,174,689,638,684, is 1.
Now, the common factors can be found like this.
195:3x 5x 13
174:2x 3x 29
689:13x 53
638:2x 11x 29
684:2x 2x 3x 3x 19
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 3x 3x 13x 29 = 13572
Therefore, the value for common factors is 13572.
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 = 10201871805840/(1x13572)
LCM = 10201871805840/13572
LCM = 751685220
Thus, we can understand that the LCM of 195,174,689,638,684 is 751685220.
