Given numbers are 665,242,654,407,505
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 665,242,654,407,505 is 196656299070.
Find LCM of 665,242,654,407,505 with Prime Factorization
2 | 665, 242, 654, 407, 505 |
5 | 665, 121, 327, 407, 505 |
11 | 133, 121, 327, 407, 101 |
133, 11, 327, 37, 101 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 11 x 133 x 11 x 327 x 37 x 101 = 196656299070
Therefore, the lowest common multiple of 665,242,654,407,505 is 196656299070.
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.
665 x 242 x 654 x 407 x 505 = 21632192897700
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.
665 : 1, 5, 7, 19, 35, 95, 133, 665
242 : 1, 2, 11, 22, 121, 242
654 : 1, 2, 3, 6, 109, 218, 327, 654
407 : 1, 11, 37, 407
505 : 1, 5, 101, 505
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 665,242,654,407,505, is 1.
Now, the common factors can be found like this.
665:5x 7x 19
242:2x 11x 11
654:2x 3x 109
407:11x 37
505:5x 101
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 11 = 110
Therefore, the value for common factors is 110.
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 = 21632192897700/(1x110)
LCM = 21632192897700/110
LCM = 196656299070
Thus, we can understand that the LCM of 665,242,654,407,505 is 196656299070.
