Find LCM of 612,187,695,689,278 with Prime Factorization
| 2 | 612, 187, 695, 689, 278 |
| 17 | 306, 187, 695, 689, 139 |
| 139 | 18, 11, 695, 689, 139 |
| 18, 11, 5, 689, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 17 x 139 x 18 x 11 x 5 x 689 x 1 = 3223651860
Therefore, the lowest common multiple of 612,187,695,689,278 is 3223651860.
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.
612 x 187 x 695 x 689 x 278 = 15234978690360
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.
612 : 1, 2, 3, 4, 6, 9, 12, 17, 18, 34, 36, 51, 68, 102, 153, 204, 306, 612
187 : 1, 11, 17, 187
695 : 1, 5, 139, 695
689 : 1, 13, 53, 689
278 : 1, 2, 139, 278
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 612,187,695,689,278, is 1.
Now, the common factors can be found like this.
612:2x 2x 3x 3x 17
187:11x 17
695:5x 139
689:13x 53
278:2x 139
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 17x 139 = 4726
Therefore, the value for common factors is 4726.
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 = 15234978690360/(1x4726)
LCM = 15234978690360/4726
LCM = 3223651860
Thus, we can understand that the LCM of 612,187,695,689,278 is 3223651860.
