Given numbers are 820,136,992,910
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 820,136,992,910 is 314597920.
Find LCM of 820,136,992,910 with Prime Factorization
2 | 820, 136, 992, 910 |
2 | 410, 68, 496, 455 |
2 | 205, 34, 248, 455 |
5 | 205, 17, 124, 455 |
41, 17, 124, 91 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 5 x 41 x 17 x 124 x 91 = 314597920
Therefore, the lowest common multiple of 820,136,992,910 is 314597920.
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.
820 x 136 x 992 x 910 = 100671334400
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.
820 : 1, 2, 4, 5, 10, 20, 41, 82, 164, 205, 410, 820
136 : 1, 2, 4, 8, 17, 34, 68, 136
992 : 1, 2, 4, 8, 16, 31, 32, 62, 124, 248, 496, 992
910 : 1, 2, 5, 7, 10, 13, 14, 26, 35, 65, 70, 91, 130, 182, 455, 910
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 820,136,992,910, is 2.
Now, the common factors can be found like this.
820:2x 2x 5x 41
136:2x 2x 2x 17
992:2x 2x 2x 2x 2x 31
910:2x 5x 7x 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 2x 2x 5 = 160
Therefore, the value for common factors is 160.
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 = 100671334400/(2x160)
LCM = 100671334400/320
LCM = 314597920
Thus, we can understand that the LCM of 820,136,992,910 is 314597920.
