Given numbers are 689,953,728,301,766
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 689,953,728,301,766 is 605574220888.
Find LCM of 689,953,728,301,766 with Prime Factorization
| 2 | 689, 953, 728, 301, 766 |
| 7 | 689, 953, 364, 301, 383 |
| 13 | 689, 953, 52, 43, 383 |
| 53, 953, 4, 43, 383 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 13 x 53 x 953 x 4 x 43 x 383 = 605574220888
Therefore, the lowest common multiple of 689,953,728,301,766 is 605574220888.
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.
689 x 953 x 728 x 301 x 766 = 110214508201616
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.
689 : 1, 13, 53, 689
953 : 1, 953
728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728
301 : 1, 7, 43, 301
766 : 1, 2, 383, 766
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 689,953,728,301,766, is 1.
Now, the common factors can be found like this.
689:13x 53
953:953
728:2x 2x 2x 7x 13
301:7x 43
766:2x 383
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 7x 13 = 182
Therefore, the value for common factors is 182.
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 = 110214508201616/(1x182)
LCM = 110214508201616/182
LCM = 605574220888
Thus, we can understand that the LCM of 689,953,728,301,766 is 605574220888.
