Given numbers are 721,889,138,717,175
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 721,889,138,717,175 is 75501569850.
Find LCM of 721,889,138,717,175 with Prime Factorization
3 | 721, 889, 138, 717, 175 |
7 | 721, 889, 46, 239, 175 |
103, 127, 46, 239, 25 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 103 x 127 x 46 x 239 x 25 = 75501569850
Therefore, the lowest common multiple of 721,889,138,717,175 is 75501569850.
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.
721 x 889 x 138 x 717 x 175 = 11098730767950
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.
721 : 1, 7, 103, 721
889 : 1, 7, 127, 889
138 : 1, 2, 3, 6, 23, 46, 69, 138
717 : 1, 3, 239, 717
175 : 1, 5, 7, 25, 35, 175
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 721,889,138,717,175, is 1.
Now, the common factors can be found like this.
721:7x 103
889:7x 127
138:2x 3x 23
717:3x 239
175:5x 5x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 7x 7 = 147
Therefore, the value for common factors is 147.
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 = 11098730767950/(1x147)
LCM = 11098730767950/147
LCM = 75501569850
Thus, we can understand that the LCM of 721,889,138,717,175 is 75501569850.
