Given numbers are 161,991,342,916,736
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 161,991,342,916,736 is 199931443488.
Find LCM of 161,991,342,916,736 with Prime Factorization
| 2 | 161, 991, 342, 916, 736 |
| 2 | 161, 991, 171, 458, 368 |
| 23 | 161, 991, 171, 229, 184 |
| 7, 991, 171, 229, 8 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 23 x 7 x 991 x 171 x 229 x 8 = 199931443488
Therefore, the lowest common multiple of 161,991,342,916,736 is 199931443488.
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 991 x 342 x 916 x 736 = 36787385601792
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
991 : 1, 991
342 : 1, 2, 3, 6, 9, 18, 19, 38, 57, 114, 171, 342
916 : 1, 2, 4, 229, 458, 916
736 : 1, 2, 4, 8, 16, 23, 32, 46, 92, 184, 368, 736
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 161,991,342,916,736, is 1.
Now, the common factors can be found like this.
161:7x 23
991:991
342:2x 3x 3x 19
916:2x 2x 229
736:2x 2x 2x 2x 2x 23
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 23 = 184
Therefore, the value for common factors is 184.
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 = 36787385601792/(1x184)
LCM = 36787385601792/184
LCM = 199931443488
Thus, we can understand that the LCM of 161,991,342,916,736 is 199931443488.
