Given numbers are 987,955,475,705,550
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 987,955,475,705,550 is 1970002650.
Find LCM of 987,955,475,705,550 with Prime Factorization
| 3 | 987, 955, 475, 705, 550 |
| 5 | 329, 955, 475, 235, 550 |
| 5 | 329, 191, 95, 47, 110 |
| 47 | 329, 191, 19, 47, 22 |
| 7, 191, 19, 1, 22 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 5 x 47 x 7 x 191 x 19 x 1 x 22 = 1970002650
Therefore, the lowest common multiple of 987,955,475,705,550 is 1970002650.
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.
987 x 955 x 475 x 705 x 550 = 173606483531250
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.
987 : 1, 3, 7, 21, 47, 141, 329, 987
955 : 1, 5, 191, 955
475 : 1, 5, 19, 25, 95, 475
705 : 1, 3, 5, 15, 47, 141, 235, 705
550 : 1, 2, 5, 10, 11, 22, 25, 50, 55, 110, 275, 550
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 987,955,475,705,550, is 1.
Now, the common factors can be found like this.
987:3x 7x 47
955:5x 191
475:5x 5x 19
705:3x 5x 47
550:2x 5x 5x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5x 5x 5x 5x 47 = 88125
Therefore, the value for common factors is 88125.
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 = 173606483531250/(1x88125)
LCM = 173606483531250/88125
LCM = 1970002650
Thus, we can understand that the LCM of 987,955,475,705,550 is 1970002650.
