Given numbers are 133,474,781,693
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 133,474,781,693 is 147707406.
Find LCM of 133,474,781,693 with Prime Factorization
| 3 | 133, 474, 781, 693 |
| 7 | 133, 158, 781, 231 |
| 11 | 19, 158, 781, 33 |
| 19, 158, 71, 3 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 11 x 19 x 158 x 71 x 3 = 147707406
Therefore, the lowest common multiple of 133,474,781,693 is 147707406.
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.
133 x 474 x 781 x 693 = 34120410786
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.
133 : 1, 7, 19, 133
474 : 1, 2, 3, 6, 79, 158, 237, 474
781 : 1, 11, 71, 781
693 : 1, 3, 7, 9, 11, 21, 33, 63, 77, 99, 231, 693
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 133,474,781,693, is 1.
Now, the common factors can be found like this.
133:7x 19
474:2x 3x 79
781:11x 71
693:3x 3x 7x 11
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 11 = 231
Therefore, the value for common factors is 231.
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 = 34120410786/(1x231)
LCM = 34120410786/231
LCM = 147707406
Thus, we can understand that the LCM of 133,474,781,693 is 147707406.
