Given numbers are 862,720,136,802,853
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 862,720,136,802,853 is 1804480078320.
Find LCM of 862,720,136,802,853 with Prime Factorization
| 2 | 862, 720, 136, 802, 853 |
| 2 | 431, 360, 68, 401, 853 |
| 2 | 431, 180, 34, 401, 853 |
| 431, 90, 17, 401, 853 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 431 x 90 x 17 x 401 x 853 = 1804480078320
Therefore, the lowest common multiple of 862,720,136,802,853 is 1804480078320.
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.
862 x 720 x 136 x 802 x 853 = 57743362506240
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.
862 : 1, 2, 431, 862
720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720
136 : 1, 2, 4, 8, 17, 34, 68, 136
802 : 1, 2, 401, 802
853 : 1, 853
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 862,720,136,802,853, is 1.
Now, the common factors can be found like this.
862:2x 431
720:2x 2x 2x 2x 3x 3x 5
136:2x 2x 2x 17
802:2x 401
853:853
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 2 = 32
Therefore, the value for common factors is 32.
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 = 57743362506240/(1x32)
LCM = 57743362506240/32
LCM = 1804480078320
Thus, we can understand that the LCM of 862,720,136,802,853 is 1804480078320.
