Find LCM of 652,784,678,717,842 with Prime Factorization
2 | 652, 784, 678, 717, 842 |
2 | 326, 392, 339, 717, 421 |
3 | 163, 196, 339, 717, 421 |
163, 196, 113, 239, 421 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 163 x 196 x 113 x 239 x 421 = 4358964801072
Therefore, the lowest common multiple of 652,784,678,717,842 is 4358964801072.
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.
652 x 784 x 678 x 717 x 842 = 209230310451456
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.
652 : 1, 2, 4, 163, 326, 652
784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784
678 : 1, 2, 3, 6, 113, 226, 339, 678
717 : 1, 3, 239, 717
842 : 1, 2, 421, 842
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 652,784,678,717,842, is 1.
Now, the common factors can be found like this.
652:2x 2x 163
784:2x 2x 2x 2x 7x 7
678:2x 3x 113
717:3x 239
842:2x 421
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 3 = 48
Therefore, the value for common factors is 48.
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 = 209230310451456/(1x48)
LCM = 209230310451456/48
LCM = 4358964801072
Thus, we can understand that the LCM of 652,784,678,717,842 is 4358964801072.
