The LCM of 767,992,391,976 is 18147367264.
Find LCM of 767,992,391,976 with Prime Factorization
| 2 | 767, 992, 391, 976 |
| 2 | 767, 496, 391, 488 |
| 2 | 767, 248, 391, 244 |
| 2 | 767, 124, 391, 122 |
| 767, 62, 391, 61 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 767 x 62 x 391 x 61 = 18147367264
Therefore, the lowest common multiple of 767,992,391,976 is 18147367264.
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 992 x 391 x 976 = 290357876224
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
992 : 1, 2, 4, 8, 16, 31, 32, 62, 124, 248, 496, 992
391 : 1, 17, 23, 391
976 : 1, 2, 4, 8, 16, 61, 122, 244, 488, 976
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 767,992,391,976, is 1.
Now, the common factors can be found like this.
767:13x 59
992:2x 2x 2x 2x 2x 31
391:17x 23
976:2x 2x 2x 2x 61
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 2 = 16
Therefore, the value for common factors is 16.
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 = 290357876224/(1x16)
LCM = 290357876224/16
LCM = 18147367264
Thus, we can understand that the LCM of 767,992,391,976 is 18147367264.
