Given numbers are 555,980,206,970,173
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 555,980,206,970,173 is 188020029540.
Find LCM of 555,980,206,970,173 with Prime Factorization
| 2 | 555, 980, 206, 970, 173 |
| 5 | 555, 490, 103, 485, 173 |
| 111, 98, 103, 97, 173 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 111 x 98 x 103 x 97 x 173 = 188020029540
Therefore, the lowest common multiple of 555,980,206,970,173 is 188020029540.
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.
555 x 980 x 206 x 970 x 173 = 18802002954000
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.
555 : 1, 3, 5, 15, 37, 111, 185, 555
980 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 49, 70, 98, 140, 196, 245, 490, 980
206 : 1, 2, 103, 206
970 : 1, 2, 5, 10, 97, 194, 485, 970
173 : 1, 173
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 555,980,206,970,173, is 1.
Now, the common factors can be found like this.
555:3x 5x 37
980:2x 2x 5x 7x 7
206:2x 103
970:2x 5x 97
173:173
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 5x 5 = 100
Therefore, the value for common factors is 100.
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 = 18802002954000/(1x100)
LCM = 18802002954000/100
LCM = 188020029540
Thus, we can understand that the LCM of 555,980,206,970,173 is 188020029540.
