Given numbers are 191,820,840,402
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 191,820,840,402 is 440728680.
Find LCM of 191,820,840,402 with Prime Factorization
2 | 191, 820, 840, 402 |
2 | 191, 410, 420, 201 |
3 | 191, 205, 210, 201 |
5 | 191, 205, 70, 67 |
191, 41, 14, 67 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 191 x 41 x 14 x 67 = 440728680
Therefore, the lowest common multiple of 191,820,840,402 is 440728680.
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.
191 x 820 x 840 x 402 = 52887441600
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.
191 : 1, 191
820 : 1, 2, 4, 5, 10, 20, 41, 82, 164, 205, 410, 820
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
402 : 1, 2, 3, 6, 67, 134, 201, 402
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 191,820,840,402, is 1.
Now, the common factors can be found like this.
191:191
820:2x 2x 5x 41
840:2x 2x 2x 3x 5x 7
402:2x 3x 67
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 3x 5 = 120
Therefore, the value for common factors is 120.
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 = 52887441600/(1x120)
LCM = 52887441600/120
LCM = 440728680
Thus, we can understand that the LCM of 191,820,840,402 is 440728680.
