Given numbers are 423,709,505,689,546
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 423,709,505,689,546 is 1460915975610.
Find LCM of 423,709,505,689,546 with Prime Factorization
| 3 | 423, 709, 505, 689, 546 |
| 13 | 141, 709, 505, 689, 182 |
| 141, 709, 505, 53, 14 |
Multiply the prime numbers at the bottom and the left side.
3 x 13 x 141 x 709 x 505 x 53 x 14 = 1460915975610
Therefore, the lowest common multiple of 423,709,505,689,546 is 1460915975610.
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.
423 x 709 x 505 x 689 x 546 = 56975723048790
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.
423 : 1, 3, 9, 47, 141, 423
709 : 1, 709
505 : 1, 5, 101, 505
689 : 1, 13, 53, 689
546 : 1, 2, 3, 6, 7, 13, 14, 21, 26, 39, 42, 78, 91, 182, 273, 546
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 423,709,505,689,546, is 1.
Now, the common factors can be found like this.
423:3x 3x 47
709:709
505:5x 101
689:13x 53
546:2x 3x 7x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 13 = 39
Therefore, the value for common factors is 39.
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 = 56975723048790/(1x39)
LCM = 56975723048790/39
LCM = 1460915975610
Thus, we can understand that the LCM of 423,709,505,689,546 is 1460915975610.
