Given numbers are 406,305,690,538,234
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 406,305,690,538,234 is 89637936570.
Find LCM of 406,305,690,538,234 with Prime Factorization
| 2 | 406, 305, 690, 538, 234 |
| 3 | 203, 305, 345, 269, 117 |
| 5 | 203, 305, 115, 269, 39 |
| 203, 61, 23, 269, 39 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 203 x 61 x 23 x 269 x 39 = 89637936570
Therefore, the lowest common multiple of 406,305,690,538,234 is 89637936570.
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.
406 x 305 x 690 x 538 x 234 = 10756552388400
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.
406 : 1, 2, 7, 14, 29, 58, 203, 406
305 : 1, 5, 61, 305
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
538 : 1, 2, 269, 538
234 : 1, 2, 3, 6, 9, 13, 18, 26, 39, 78, 117, 234
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 406,305,690,538,234, is 1.
Now, the common factors can be found like this.
406:2x 7x 29
305:5x 61
690:2x 3x 5x 23
538:2x 269
234:2x 3x 3x 13
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 3x 5 = 120
Therefore, the value for common factors is 120.
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 = 10756552388400/(1x120)
LCM = 10756552388400/120
LCM = 89637936570
Thus, we can understand that the LCM of 406,305,690,538,234 is 89637936570.
