Find LCM of 780,520,961,899,463 with Prime Factorization
2 | 780, 520, 961, 899, 463 |
2 | 390, 260, 961, 899, 463 |
5 | 195, 130, 961, 899, 463 |
13 | 39, 26, 961, 899, 463 |
31 | 3, 2, 961, 899, 463 |
3, 2, 31, 29, 463 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 13 x 31 x 3 x 2 x 31 x 29 x 463 = 20129221320
Therefore, the lowest common multiple of 780,520,961,899,463 is 20129221320.
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 520 x 961 x 899 x 463 = 162241523839200
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
520 : 1, 2, 4, 5, 8, 10, 13, 20, 26, 40, 52, 65, 104, 130, 260, 520
961 : 1, 31, 961
899 : 1, 29, 31, 899
463 : 1, 463
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 780,520,961,899,463, is 1.
Now, the common factors can be found like this.
780:2x 2x 3x 5x 13
520:2x 2x 2x 5x 13
961:31x 31
899:29x 31
463:463
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 5x 13x 31 = 8060
Therefore, the value for common factors is 8060.
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 = 162241523839200/(1x8060)
LCM = 162241523839200/8060
LCM = 20129221320
Thus, we can understand that the LCM of 780,520,961,899,463 is 20129221320.
