Find LCM of 784,931,403,845,956 with Prime Factorization
| 2 | 784, 931, 403, 845, 956 |
| 2 | 392, 931, 403, 845, 478 |
| 7 | 196, 931, 403, 845, 239 |
| 7 | 28, 133, 403, 845, 239 |
| 13 | 4, 19, 403, 845, 239 |
| 4, 19, 31, 65, 239 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 7 x 13 x 4 x 19 x 31 x 65 x 239 = 93257972080
Therefore, the lowest common multiple of 784,931,403,845,956 is 93257972080.
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.
784 x 931 x 403 x 845 x 956 = 237621312859840
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.
784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784
931 : 1, 7, 19, 49, 133, 931
403 : 1, 13, 31, 403
845 : 1, 5, 13, 65, 169, 845
956 : 1, 2, 4, 239, 478, 956
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 784,931,403,845,956, is 1.
Now, the common factors can be found like this.
784:2x 2x 2x 2x 7x 7
931:7x 7x 19
403:13x 31
845:5x 13x 13
956:2x 2x 239
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 7x 7x 13 = 2548
Therefore, the value for common factors is 2548.
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 = 237621312859840/(1x2548)
LCM = 237621312859840/2548
LCM = 93257972080
Thus, we can understand that the LCM of 784,931,403,845,956 is 93257972080.
