Given numbers are 605,786,961,664
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 605,786,961,664 is 151718797560.
Find LCM of 605,786,961,664 with Prime Factorization
2 | 605, 786, 961, 664 |
605, 393, 961, 332 |
Multiply the prime numbers at the bottom and the left side.
2 x 605 x 393 x 961 x 332 = 151718797560
Therefore, the lowest common multiple of 605,786,961,664 is 151718797560.
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.
605 x 786 x 961 x 664 = 303437595120
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.
605 : 1, 5, 11, 55, 121, 605
786 : 1, 2, 3, 6, 131, 262, 393, 786
961 : 1, 31, 961
664 : 1, 2, 4, 8, 83, 166, 332, 664
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 605,786,961,664, is 1.
Now, the common factors can be found like this.
605:5x 11x 11
786:2x 3x 131
961:31x 31
664:2x 2x 2x 83
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2 = 2
Therefore, the value for common factors is 2.
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 = 303437595120/(1x2)
LCM = 303437595120/2
LCM = 151718797560
Thus, we can understand that the LCM of 605,786,961,664 is 151718797560.
