Given numbers are 686,152,521,679,590
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 686,152,521,679,590 is 777265124440.
Find LCM of 686,152,521,679,590 with Prime Factorization
| 2 | 686, 152, 521, 679, 590 |
| 7 | 343, 76, 521, 679, 295 |
| 49, 76, 521, 97, 295 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 49 x 76 x 521 x 97 x 295 = 777265124440
Therefore, the lowest common multiple of 686,152,521,679,590 is 777265124440.
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.
686 x 152 x 521 x 679 x 590 = 21763423484320
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.
686 : 1, 2, 7, 14, 49, 98, 343, 686
152 : 1, 2, 4, 8, 19, 38, 76, 152
521 : 1, 521
679 : 1, 7, 97, 679
590 : 1, 2, 5, 10, 59, 118, 295, 590
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 686,152,521,679,590, is 1.
Now, the common factors can be found like this.
686:2x 7x 7x 7
152:2x 2x 2x 19
521:521
679:7x 97
590:2x 5x 59
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 7 = 28
Therefore, the value for common factors is 28.
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 = 21763423484320/(1x28)
LCM = 21763423484320/28
LCM = 777265124440
Thus, we can understand that the LCM of 686,152,521,679,590 is 777265124440.
