Given numbers are 437,138,386,718,943
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 437,138,386,718,943 is 7448491074.
Find LCM of 437,138,386,718,943 with Prime Factorization
| 2 | 437, 138, 386, 718, 943 |
| 23 | 437, 69, 193, 359, 943 |
| 19, 3, 193, 359, 41 |
Multiply the prime numbers at the bottom and the left side.
2 x 23 x 19 x 3 x 193 x 359 x 41 = 7448491074
Therefore, the lowest common multiple of 437,138,386,718,943 is 7448491074.
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.
437 x 138 x 386 x 718 x 943 = 15761007112584
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.
437 : 1, 19, 23, 437
138 : 1, 2, 3, 6, 23, 46, 69, 138
386 : 1, 2, 193, 386
718 : 1, 2, 359, 718
943 : 1, 23, 41, 943
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 437,138,386,718,943, is 1.
Now, the common factors can be found like this.
437:19x 23
138:2x 3x 23
386:2x 193
718:2x 359
943:23x 41
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 23x 23 = 2116
Therefore, the value for common factors is 2116.
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 = 15761007112584/(1x2116)
LCM = 15761007112584/2116
LCM = 7448491074
Thus, we can understand that the LCM of 437,138,386,718,943 is 7448491074.
