Given numbers are 161,655,781,696,407
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 161,655,781,696,407 is 2120943861960.
Find LCM of 161,655,781,696,407 with Prime Factorization
11 | 161, 655, 781, 696, 407 |
161, 655, 71, 696, 37 |
Multiply the prime numbers at the bottom and the left side.
11 x 161 x 655 x 71 x 696 x 37 = 2120943861960
Therefore, the lowest common multiple of 161,655,781,696,407 is 2120943861960.
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.
161 x 655 x 781 x 696 x 407 = 23330382481560
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.
161 : 1, 7, 23, 161
655 : 1, 5, 131, 655
781 : 1, 11, 71, 781
696 : 1, 2, 3, 4, 6, 8, 12, 24, 29, 58, 87, 116, 174, 232, 348, 696
407 : 1, 11, 37, 407
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 161,655,781,696,407, is 1.
Now, the common factors can be found like this.
161:7x 23
655:5x 131
781:11x 71
696:2x 2x 2x 3x 29
407:11x 37
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
11 = 11
Therefore, the value for common factors is 11.
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 = 23330382481560/(1x11)
LCM = 23330382481560/11
LCM = 2120943861960
Thus, we can understand that the LCM of 161,655,781,696,407 is 2120943861960.
