Find LCM of 936,770,378,638 with Prime Factorization
2 | 936, 770, 378, 638 |
3 | 468, 385, 189, 319 |
3 | 156, 385, 63, 319 |
7 | 52, 385, 21, 319 |
11 | 52, 55, 3, 319 |
52, 5, 3, 29 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 7 x 11 x 52 x 5 x 3 x 29 = 31351320
Therefore, the lowest common multiple of 936,770,378,638 is 31351320.
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.
936 x 770 x 378 x 638 = 173811718080
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.
936 : 1, 2, 3, 4, 6, 8, 9, 12, 13, 18, 24, 26, 36, 39, 52, 72, 78, 104, 117, 156, 234, 312, 468, 936
770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770
378 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 27, 42, 54, 63, 126, 189, 378
638 : 1, 2, 11, 22, 29, 58, 319, 638
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 936,770,378,638, is 2.
Now, the common factors can be found like this.
936:2x 2x 2x 3x 3x 13
770:2x 5x 7x 11
378:2x 3x 3x 3x 7
638:2x 11x 29
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 7x 11 = 2772
Therefore, the value for common factors is 2772.
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 = 173811718080/(2x2772)
LCM = 173811718080/5544
LCM = 31351320
Thus, we can understand that the LCM of 936,770,378,638 is 31351320.
