Given numbers are 275,129,129,644,971
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 275,129,129,644,971 is 22183368900.
Find LCM of 275,129,129,644,971 with Prime Factorization
3 | 275, 129, 129, 644, 971 |
43 | 275, 43, 43, 644, 971 |
275, 1, 1, 644, 971 |
Multiply the prime numbers at the bottom and the left side.
3 x 43 x 275 x 1 x 1 x 644 x 971 = 22183368900
Therefore, the lowest common multiple of 275,129,129,644,971 is 22183368900.
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.
275 x 129 x 129 x 644 x 971 = 2861654588100
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.
275 : 1, 5, 11, 25, 55, 275
129 : 1, 3, 43, 129
129 : 1, 3, 43, 129
644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644
971 : 1, 971
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 275,129,129,644,971, is 1.
Now, the common factors can be found like this.
275:5x 5x 11
129:3x 43
129:3x 43
644:2x 2x 7x 23
971:971
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 43 = 129
Therefore, the value for common factors is 129.
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 = 2861654588100/(1x129)
LCM = 2861654588100/129
LCM = 22183368900
Thus, we can understand that the LCM of 275,129,129,644,971 is 22183368900.
