Given numbers are 153,642,644,666,555
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 153,642,644,666,555 is 1950440940.
Find LCM of 153,642,644,666,555 with Prime Factorization
| 2 | 153, 642, 644, 666, 555 |
| 3 | 153, 321, 322, 333, 555 |
| 3 | 51, 107, 322, 111, 185 |
| 37 | 17, 107, 322, 37, 185 |
| 17, 107, 322, 1, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 37 x 17 x 107 x 322 x 1 x 5 = 1950440940
Therefore, the lowest common multiple of 153,642,644,666,555 is 1950440940.
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.
153 x 642 x 644 x 666 x 555 = 23381885988720
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.
153 : 1, 3, 9, 17, 51, 153
642 : 1, 2, 3, 6, 107, 214, 321, 642
644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644
666 : 1, 2, 3, 6, 9, 18, 37, 74, 111, 222, 333, 666
555 : 1, 3, 5, 15, 37, 111, 185, 555
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 153,642,644,666,555, is 1.
Now, the common factors can be found like this.
153:3x 3x 17
642:2x 3x 107
644:2x 2x 7x 23
666:2x 3x 3x 37
555:3x 5x 37
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 3x 3x 3x 3x 37 = 11988
Therefore, the value for common factors is 11988.
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 = 23381885988720/(1x11988)
LCM = 23381885988720/11988
LCM = 1950440940
Thus, we can understand that the LCM of 153,642,644,666,555 is 1950440940.
