Find LCM of 620,817,828,865,713 with Prime Factorization
| 2 | 620, 817, 828, 865, 713 |
| 2 | 310, 817, 414, 865, 713 |
| 5 | 155, 817, 207, 865, 713 |
| 23 | 31, 817, 207, 173, 713 |
| 31 | 31, 817, 9, 173, 31 |
| 1, 817, 9, 173, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 23 x 31 x 1 x 817 x 9 x 173 x 1 = 18139703940
Therefore, the lowest common multiple of 620,817,828,865,713 is 18139703940.
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.
620 x 817 x 828 x 865 x 713 = 258672178184400
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.
620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620
817 : 1, 19, 43, 817
828 : 1, 2, 3, 4, 6, 9, 12, 18, 23, 36, 46, 69, 92, 138, 207, 276, 414, 828
865 : 1, 5, 173, 865
713 : 1, 23, 31, 713
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 620,817,828,865,713, is 1.
Now, the common factors can be found like this.
620:2x 2x 5x 31
817:19x 43
828:2x 2x 3x 3x 23
865:5x 173
713:23x 31
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 5x 23x 31 = 14260
Therefore, the value for common factors is 14260.
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 = 258672178184400/(1x14260)
LCM = 258672178184400/14260
LCM = 18139703940
Thus, we can understand that the LCM of 620,817,828,865,713 is 18139703940.
