Find LCM of 678,981,217,370,756 with Prime Factorization
| 2 | 678, 981, 217, 370, 756 |
| 3 | 339, 981, 217, 185, 378 |
| 3 | 113, 327, 217, 185, 126 |
| 7 | 113, 109, 217, 185, 42 |
| 113, 109, 31, 185, 6 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 7 x 113 x 109 x 31 x 185 x 6 = 53402324220
Therefore, the lowest common multiple of 678,981,217,370,756 is 53402324220.
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.
678 x 981 x 217 x 370 x 756 = 40372157110320
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.
678 : 1, 2, 3, 6, 113, 226, 339, 678
981 : 1, 3, 9, 109, 327, 981
217 : 1, 7, 31, 217
370 : 1, 2, 5, 10, 37, 74, 185, 370
756 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 27, 28, 36, 42, 54, 63, 84, 108, 126, 189, 252, 378, 756
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 678,981,217,370,756, is 1.
Now, the common factors can be found like this.
678:2x 3x 113
981:3x 3x 109
217:7x 31
370:2x 5x 37
756:2x 2x 3x 3x 3x 7
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 3x 7 = 756
Therefore, the value for common factors is 756.
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 = 40372157110320/(1x756)
LCM = 40372157110320/756
LCM = 53402324220
Thus, we can understand that the LCM of 678,981,217,370,756 is 53402324220.
