Find LCM of 644,713,124,142,818 with Prime Factorization
2 | 644, 713, 124, 142, 818 |
2 | 322, 713, 62, 71, 409 |
23 | 161, 713, 31, 71, 409 |
31 | 7, 31, 31, 71, 409 |
7, 1, 1, 71, 409 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 23 x 31 x 7 x 1 x 1 x 71 x 409 = 579734596
Therefore, the lowest common multiple of 644,713,124,142,818 is 579734596.
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.
644 x 713 x 124 x 142 x 818 = 6613612271168
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.
644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644
713 : 1, 23, 31, 713
124 : 1, 2, 4, 31, 62, 124
142 : 1, 2, 71, 142
818 : 1, 2, 409, 818
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 644,713,124,142,818, is 1.
Now, the common factors can be found like this.
644:2x 2x 7x 23
713:23x 31
124:2x 2x 31
142:2x 71
818:2x 409
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 23x 31 = 11408
Therefore, the value for common factors is 11408.
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 = 6613612271168/(1x11408)
LCM = 6613612271168/11408
LCM = 579734596
Thus, we can understand that the LCM of 644,713,124,142,818 is 579734596.
