Find LCM of 931,759,220,621,517 with Prime Factorization
| 3 | 931, 759, 220, 621, 517 |
| 11 | 931, 253, 220, 207, 517 |
| 23 | 931, 23, 20, 207, 47 |
| 931, 1, 20, 9, 47 |
Multiply the prime numbers at the bottom and the left side.
3 x 11 x 23 x 931 x 1 x 20 x 9 x 47 = 5978081340
Therefore, the lowest common multiple of 931,759,220,621,517 is 5978081340.
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.
931 x 759 x 220 x 621 x 517 = 49911001107660
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.
931 : 1, 7, 19, 49, 133, 931
759 : 1, 3, 11, 23, 33, 69, 253, 759
220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220
621 : 1, 3, 9, 23, 27, 69, 207, 621
517 : 1, 11, 47, 517
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 931,759,220,621,517, is 1.
Now, the common factors can be found like this.
931:7x 7x 19
759:3x 11x 23
220:2x 2x 5x 11
621:3x 3x 3x 23
517:11x 47
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 11x 11x 23 = 8349
Therefore, the value for common factors is 8349.
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 = 49911001107660/(1x8349)
LCM = 49911001107660/8349
LCM = 5978081340
Thus, we can understand that the LCM of 931,759,220,621,517 is 5978081340.
