Given numbers are 699,816,780,868,157
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 699,816,780,868,157 is 421035604080.
Find LCM of 699,816,780,868,157 with Prime Factorization
| 2 | 699, 816, 780, 868, 157 |
| 2 | 699, 408, 390, 434, 157 |
| 3 | 699, 204, 195, 217, 157 |
| 233, 68, 65, 217, 157 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 233 x 68 x 65 x 217 x 157 = 421035604080
Therefore, the lowest common multiple of 699,816,780,868,157 is 421035604080.
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.
699 x 816 x 780 x 868 x 157 = 60629126987520
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.
699 : 1, 3, 233, 699
816 : 1, 2, 3, 4, 6, 8, 12, 16, 17, 24, 34, 48, 51, 68, 102, 136, 204, 272, 408, 816
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
868 : 1, 2, 4, 7, 14, 28, 31, 62, 124, 217, 434, 868
157 : 1, 157
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 699,816,780,868,157, is 1.
Now, the common factors can be found like this.
699:3x 233
816:2x 2x 2x 2x 3x 17
780:2x 2x 3x 5x 13
868:2x 2x 7x 31
157:157
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 3x 3 = 144
Therefore, the value for common factors is 144.
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 = 60629126987520/(1x144)
LCM = 60629126987520/144
LCM = 421035604080
Thus, we can understand that the LCM of 699,816,780,868,157 is 421035604080.
