Find LCM of 878,378,931,640,632 with Prime Factorization
| 2 | 878, 378, 931, 640, 632 |
| 2 | 439, 189, 931, 320, 316 |
| 2 | 439, 189, 931, 160, 158 |
| 7 | 439, 189, 931, 80, 79 |
| 439, 27, 133, 80, 79 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 7 x 439 x 27 x 133 x 80 x 79 = 557936830080
Therefore, the lowest common multiple of 878,378,931,640,632 is 557936830080.
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.
878 x 378 x 931 x 640 x 632 = 124977849937920
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.
878 : 1, 2, 439, 878
378 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 27, 42, 54, 63, 126, 189, 378
931 : 1, 7, 19, 49, 133, 931
640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640
632 : 1, 2, 4, 8, 79, 158, 316, 632
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 878,378,931,640,632, is 1.
Now, the common factors can be found like this.
878:2x 439
378:2x 3x 3x 3x 7
931:7x 7x 19
640:2x 2x 2x 2x 2x 2x 2x 5
632:2x 2x 2x 79
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 2x 2x 2x 7 = 224
Therefore, the value for common factors is 224.
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 = 124977849937920/(1x224)
LCM = 124977849937920/224
LCM = 557936830080
Thus, we can understand that the LCM of 878,378,931,640,632 is 557936830080.
