Given numbers are 377,641,638,905
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 377,641,638,905 is 4811390870.
Find LCM of 377,641,638,905 with Prime Factorization
29 | 377, 641, 638, 905 |
13, 641, 22, 905 |
Multiply the prime numbers at the bottom and the left side.
29 x 13 x 641 x 22 x 905 = 4811390870
Therefore, the lowest common multiple of 377,641,638,905 is 4811390870.
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.
377 x 641 x 638 x 905 = 139530335230
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.
377 : 1, 13, 29, 377
641 : 1, 641
638 : 1, 2, 11, 22, 29, 58, 319, 638
905 : 1, 5, 181, 905
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 377,641,638,905, is 1.
Now, the common factors can be found like this.
377:13x 29
641:641
638:2x 11x 29
905:5x 181
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
29 = 29
Therefore, the value for common factors is 29.
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 = 139530335230/(1x29)
LCM = 139530335230/29
LCM = 4811390870
Thus, we can understand that the LCM of 377,641,638,905 is 4811390870.
