Find LCM of 217,969,453,760,780 with Prime Factorization
| 2 | 217, 969, 453, 760, 780 |
| 2 | 217, 969, 453, 380, 390 |
| 3 | 217, 969, 453, 190, 195 |
| 5 | 217, 323, 151, 190, 65 |
| 19 | 217, 323, 151, 38, 13 |
| 217, 17, 151, 2, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 19 x 217 x 17 x 151 x 2 x 13 = 16510635960
Therefore, the lowest common multiple of 217,969,453,760,780 is 16510635960.
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.
217 x 969 x 453 x 760 x 780 = 56466374983200
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.
217 : 1, 7, 31, 217
969 : 1, 3, 17, 19, 51, 57, 323, 969
453 : 1, 3, 151, 453
760 : 1, 2, 4, 5, 8, 10, 19, 20, 38, 40, 76, 95, 152, 190, 380, 760
780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 217,969,453,760,780, is 1.
Now, the common factors can be found like this.
217:7x 31
969:3x 17x 19
453:3x 151
760:2x 2x 2x 5x 19
780:2x 2x 3x 5x 13
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 3x 3x 5x 19 = 3420
Therefore, the value for common factors is 3420.
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 = 56466374983200/(1x3420)
LCM = 56466374983200/3420
LCM = 16510635960
Thus, we can understand that the LCM of 217,969,453,760,780 is 16510635960.
