Find LCM of 782,495,231,765,254 with Prime Factorization
| 2 | 782, 495, 231, 765, 254 |
| 3 | 391, 495, 231, 765, 127 |
| 3 | 391, 165, 77, 255, 127 |
| 5 | 391, 55, 77, 85, 127 |
| 11 | 391, 11, 77, 17, 127 |
| 17 | 391, 1, 7, 17, 127 |
| 23, 1, 7, 1, 127 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 5 x 11 x 17 x 23 x 1 x 7 x 1 x 127 = 344123010
Therefore, the lowest common multiple of 782,495,231,765,254 is 344123010.
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.
782 x 495 x 231 x 765 x 254 = 17374770774900
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.
782 : 1, 2, 17, 23, 34, 46, 391, 782
495 : 1, 3, 5, 9, 11, 15, 33, 45, 55, 99, 165, 495
231 : 1, 3, 7, 11, 21, 33, 77, 231
765 : 1, 3, 5, 9, 15, 17, 45, 51, 85, 153, 255, 765
254 : 1, 2, 127, 254
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 782,495,231,765,254, is 1.
Now, the common factors can be found like this.
782:2x 17x 23
495:3x 3x 5x 11
231:3x 7x 11
765:3x 3x 5x 17
254:2x 127
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 3x 5x 11x 17 = 50490
Therefore, the value for common factors is 50490.
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 = 17374770774900/(1x50490)
LCM = 17374770774900/50490
LCM = 344123010
Thus, we can understand that the LCM of 782,495,231,765,254 is 344123010.
