Find LCM of 637,361,378,702 with Prime Factorization
| 2 | 637, 361, 378, 702 |
| 3 | 637, 361, 189, 351 |
| 3 | 637, 361, 63, 117 |
| 3 | 637, 361, 21, 39 |
| 7 | 637, 361, 7, 13 |
| 13 | 91, 361, 1, 13 |
| 7, 361, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 3 x 7 x 13 x 7 x 361 x 1 x 1 = 12417678
Therefore, the lowest common multiple of 637,361,378,702 is 12417678.
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.
637 x 361 x 378 x 702 = 61020469692
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.
637 : 1, 7, 13, 49, 91, 637
361 : 1, 19, 361
378 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 27, 42, 54, 63, 126, 189, 378
702 : 1, 2, 3, 6, 9, 13, 18, 26, 27, 39, 54, 78, 117, 234, 351, 702
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 637,361,378,702, is 1.
Now, the common factors can be found like this.
637:7x 7x 13
361:19x 19
378:2x 3x 3x 3x 7
702:2x 3x 3x 3x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 3x 7x 13 = 4914
Therefore, the value for common factors is 4914.
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 = 61020469692/(1x4914)
LCM = 61020469692/4914
LCM = 12417678
Thus, we can understand that the LCM of 637,361,378,702 is 12417678.
