The LCM of 161,406,957,963 is 98917434.
Find LCM of 161,406,957,963 with Prime Factorization
| 3 | 161, 406, 957, 963 |
| 7 | 161, 406, 319, 321 |
| 29 | 23, 58, 319, 321 |
| 23, 2, 11, 321 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 29 x 23 x 2 x 11 x 321 = 98917434
Therefore, the lowest common multiple of 161,406,957,963 is 98917434.
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 406 x 957 x 963 = 60240717306
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
406 : 1, 2, 7, 14, 29, 58, 203, 406
957 : 1, 3, 11, 29, 33, 87, 319, 957
963 : 1, 3, 9, 107, 321, 963
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 161,406,957,963, is 1.
Now, the common factors can be found like this.
161:7x 23
406:2x 7x 29
957:3x 11x 29
963:3x 3x 107
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 7x 29 = 609
Therefore, the value for common factors is 609.
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 = 60240717306/(1x609)
LCM = 60240717306/609
LCM = 98917434
Thus, we can understand that the LCM of 161,406,957,963 is 98917434.
