The LCM of 780,904,862,992,357 is 1121111890080.
Find LCM of 780,904,862,992,357 with Prime Factorization
| 2 | 780, 904, 862, 992, 357 |
| 2 | 390, 452, 431, 496, 357 |
| 2 | 195, 226, 431, 248, 357 |
| 3 | 195, 113, 431, 124, 357 |
| 65, 113, 431, 124, 119 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 65 x 113 x 431 x 124 x 119 = 1121111890080
Therefore, the lowest common multiple of 780,904,862,992,357 is 1121111890080.
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.
780 x 904 x 862 x 992 x 357 = 215253482895360
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.
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
904 : 1, 2, 4, 8, 113, 226, 452, 904
862 : 1, 2, 431, 862
992 : 1, 2, 4, 8, 16, 31, 32, 62, 124, 248, 496, 992
357 : 1, 3, 7, 17, 21, 51, 119, 357
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 780,904,862,992,357, is 1.
Now, the common factors can be found like this.
780:2x 2x 3x 5x 13
904:2x 2x 2x 113
862:2x 431
992:2x 2x 2x 2x 2x 31
357:3x 7x 17
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 2x 2x 2x 3 = 192
Therefore, the value for common factors is 192.
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 = 215253482895360/(1x192)
LCM = 215253482895360/192
LCM = 1121111890080
Thus, we can understand that the LCM of 780,904,862,992,357 is 1121111890080.
