Given numbers are 840,156,202,901,109
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 840,156,202,901,109 is 108316670280.
Find LCM of 840,156,202,901,109 with Prime Factorization
| 2 | 840, 156, 202, 901, 109 |
| 2 | 420, 78, 101, 901, 109 |
| 3 | 210, 39, 101, 901, 109 |
| 70, 13, 101, 901, 109 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 70 x 13 x 101 x 901 x 109 = 108316670280
Therefore, the lowest common multiple of 840,156,202,901,109 is 108316670280.
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.
840 x 156 x 202 x 901 x 109 = 2599600086720
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.
840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840
156 : 1, 2, 3, 4, 6, 12, 13, 26, 39, 52, 78, 156
202 : 1, 2, 101, 202
901 : 1, 17, 53, 901
109 : 1, 109
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 840,156,202,901,109, is 1.
Now, the common factors can be found like this.
840:2x 2x 2x 3x 5x 7
156:2x 2x 3x 13
202:2x 101
901:17x 53
109:109
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 3 = 24
Therefore, the value for common factors is 24.
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 = 2599600086720/(1x24)
LCM = 2599600086720/24
LCM = 108316670280
Thus, we can understand that the LCM of 840,156,202,901,109 is 108316670280.
