The LCM of 767,652,978,780 is 7501260.
Find LCM of 767,652,978,780 with Prime Factorization
| 2 | 767, 652, 978, 780 |
| 2 | 767, 326, 489, 390 |
| 3 | 767, 163, 489, 195 |
| 13 | 767, 163, 163, 65 |
| 163 | 59, 163, 163, 5 |
| 59, 1, 1, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 13 x 163 x 59 x 1 x 1 x 5 = 7501260
Therefore, the lowest common multiple of 767,652,978,780 is 7501260.
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.
767 x 652 x 978 x 780 = 381484078560
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.
767 : 1, 13, 59, 767
652 : 1, 2, 4, 163, 326, 652
978 : 1, 2, 3, 6, 163, 326, 489, 978
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 767,652,978,780, is 1.
Now, the common factors can be found like this.
767:13x 59
652:2x 2x 163
978:2x 3x 163
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 2x 3x 13x 163 = 50856
Therefore, the value for common factors is 50856.
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 = 381484078560/(1x50856)
LCM = 381484078560/50856
LCM = 7501260
Thus, we can understand that the LCM of 767,652,978,780 is 7501260.
