Find LCM of 784,881,437,708,678 with Prime Factorization
| 2 | 784, 881, 437, 708, 678 |
| 2 | 392, 881, 437, 354, 339 |
| 3 | 196, 881, 437, 177, 339 |
| 196, 881, 437, 59, 113 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 196 x 881 x 437 x 59 x 113 = 6037054797648
Therefore, the lowest common multiple of 784,881,437,708,678 is 6037054797648.
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 881 x 437 x 708 x 678 = 144889315143552
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
881 : 1, 881
437 : 1, 19, 23, 437
708 : 1, 2, 3, 4, 6, 12, 59, 118, 177, 236, 354, 708
678 : 1, 2, 3, 6, 113, 226, 339, 678
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 784,881,437,708,678, is 1.
Now, the common factors can be found like this.
784:2x 2x 2x 2x 7x 7
881:881
437:19x 23
708:2x 2x 3x 59
678:2x 3x 113
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 3 = 24
Therefore, the value for common factors is 24.
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 = 144889315143552/(1x24)
LCM = 144889315143552/24
LCM = 6037054797648
Thus, we can understand that the LCM of 784,881,437,708,678 is 6037054797648.
