Find LCM of 784,835,536,748,938 with Prime Factorization
| 2 | 784, 835, 536, 748, 938 |
| 2 | 392, 835, 268, 374, 469 |
| 2 | 196, 835, 134, 187, 469 |
| 7 | 98, 835, 67, 187, 469 |
| 67 | 14, 835, 67, 187, 67 |
| 14, 835, 1, 187, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 7 x 67 x 14 x 835 x 1 x 187 x 1 = 8201984560
Therefore, the lowest common multiple of 784,835,536,748,938 is 8201984560.
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 835 x 536 x 748 x 938 = 246190768552960
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
835 : 1, 5, 167, 835
536 : 1, 2, 4, 8, 67, 134, 268, 536
748 : 1, 2, 4, 11, 17, 22, 34, 44, 68, 187, 374, 748
938 : 1, 2, 7, 14, 67, 134, 469, 938
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 784,835,536,748,938, is 1.
Now, the common factors can be found like this.
784:2x 2x 2x 2x 7x 7
835:5x 167
536:2x 2x 2x 67
748:2x 2x 11x 17
938:2x 7x 67
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 2x 7x 67 = 30016
Therefore, the value for common factors is 30016.
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 = 246190768552960/(1x30016)
LCM = 246190768552960/30016
LCM = 8201984560
Thus, we can understand that the LCM of 784,835,536,748,938 is 8201984560.
