Given numbers are 643,363,613,278,706
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 643,363,613,278,706 is 14040984948078.
Find LCM of 643,363,613,278,706 with Prime Factorization
2 | 643, 363, 613, 278, 706 |
643, 363, 613, 139, 353 |
Multiply the prime numbers at the bottom and the left side.
2 x 643 x 363 x 613 x 139 x 353 = 14040984948078
Therefore, the lowest common multiple of 643,363,613,278,706 is 14040984948078.
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.
643 x 363 x 613 x 278 x 706 = 28081969896156
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.
643 : 1, 643
363 : 1, 3, 11, 33, 121, 363
613 : 1, 613
278 : 1, 2, 139, 278
706 : 1, 2, 353, 706
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 643,363,613,278,706, is 1.
Now, the common factors can be found like this.
643:643
363:3x 11x 11
613:613
278:2x 139
706:2x 353
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 = 28081969896156/(1x2)
LCM = 28081969896156/2
LCM = 14040984948078
Thus, we can understand that the LCM of 643,363,613,278,706 is 14040984948078.
