Find LCM of 518,896,744,782,784 with Prime Factorization
| 2 | 518, 896, 744, 782, 784 |
| 2 | 259, 448, 372, 391, 392 |
| 2 | 259, 224, 186, 391, 196 |
| 2 | 259, 112, 93, 391, 98 |
| 7 | 259, 56, 93, 391, 49 |
| 37, 8, 93, 391, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 7 x 37 x 8 x 93 x 391 x 7 = 8438543232
Therefore, the lowest common multiple of 518,896,744,782,784 is 8438543232.
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.
518 x 896 x 744 x 782 x 784 = 211706172604416
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.
518 : 1, 2, 7, 14, 37, 74, 259, 518
896 : 1, 2, 4, 7, 8, 14, 16, 28, 32, 56, 64, 112, 128, 224, 448, 896
744 : 1, 2, 3, 4, 6, 8, 12, 24, 31, 62, 93, 124, 186, 248, 372, 744
782 : 1, 2, 17, 23, 34, 46, 391, 782
784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 518,896,744,782,784, is 2.
Now, the common factors can be found like this.
518:2x 7x 37
896:2x 2x 2x 2x 2x 2x 2x 7
744:2x 2x 2x 3x 31
782:2x 17x 23
784:2x 2x 2x 2x 7x 7
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 2x 2x 7x 7 = 12544
Therefore, the value for common factors is 12544.
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 = 211706172604416/(2x12544)
LCM = 211706172604416/25088
LCM = 8438543232
Thus, we can understand that the LCM of 518,896,744,782,784 is 8438543232.
