Given numbers are 402,195,685,771,171
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 402,195,685,771,171 is 52440636690.
Find LCM of 402,195,685,771,171 with Prime Factorization
| 3 | 402, 195, 685, 771, 171 |
| 5 | 134, 65, 685, 257, 57 |
| 134, 13, 137, 257, 57 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 134 x 13 x 137 x 257 x 57 = 52440636690
Therefore, the lowest common multiple of 402,195,685,771,171 is 52440636690.
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.
402 x 195 x 685 x 771 x 171 = 7079485953150
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.
402 : 1, 2, 3, 6, 67, 134, 201, 402
195 : 1, 3, 5, 13, 15, 39, 65, 195
685 : 1, 5, 137, 685
771 : 1, 3, 257, 771
171 : 1, 3, 9, 19, 57, 171
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 402,195,685,771,171, is 1.
Now, the common factors can be found like this.
402:2x 3x 67
195:3x 5x 13
685:5x 137
771:3x 257
171:3x 3x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 3x 5 = 135
Therefore, the value for common factors is 135.
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 = 7079485953150/(1x135)
LCM = 7079485953150/135
LCM = 52440636690
Thus, we can understand that the LCM of 402,195,685,771,171 is 52440636690.
