Given numbers are 638,571,226,745,985
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 638,571,226,745,985 is 6041680144610.
Find LCM of 638,571,226,745,985 with Prime Factorization
2 | 638, 571, 226, 745, 985 |
5 | 319, 571, 113, 745, 985 |
319, 571, 113, 149, 197 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 319 x 571 x 113 x 149 x 197 = 6041680144610
Therefore, the lowest common multiple of 638,571,226,745,985 is 6041680144610.
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.
638 x 571 x 226 x 745 x 985 = 60416801446100
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.
638 : 1, 2, 11, 22, 29, 58, 319, 638
571 : 1, 571
226 : 1, 2, 113, 226
745 : 1, 5, 149, 745
985 : 1, 5, 197, 985
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 638,571,226,745,985, is 1.
Now, the common factors can be found like this.
638:2x 11x 29
571:571
226:2x 113
745:5x 149
985:5x 197
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5 = 10
Therefore, the value for common factors is 10.
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 = 60416801446100/(1x10)
LCM = 60416801446100/10
LCM = 6041680144610
Thus, we can understand that the LCM of 638,571,226,745,985 is 6041680144610.
