Given numbers are 781,619,284,589,854
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 781,619,284,589,854 is 486345435268.
Find LCM of 781,619,284,589,854 with Prime Factorization
| 2 | 781, 619, 284, 589, 854 |
| 71 | 781, 619, 142, 589, 427 |
| 11, 619, 2, 589, 427 |
Multiply the prime numbers at the bottom and the left side.
2 x 71 x 11 x 619 x 2 x 589 x 427 = 486345435268
Therefore, the lowest common multiple of 781,619,284,589,854 is 486345435268.
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.
781 x 619 x 284 x 589 x 854 = 69061051808056
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.
781 : 1, 11, 71, 781
619 : 1, 619
284 : 1, 2, 4, 71, 142, 284
589 : 1, 19, 31, 589
854 : 1, 2, 7, 14, 61, 122, 427, 854
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 781,619,284,589,854, is 1.
Now, the common factors can be found like this.
781:11x 71
619:619
284:2x 2x 71
589:19x 31
854:2x 7x 61
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 71 = 142
Therefore, the value for common factors is 142.
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 = 69061051808056/(1x142)
LCM = 69061051808056/142
LCM = 486345435268
Thus, we can understand that the LCM of 781,619,284,589,854 is 486345435268.
