The LCM of 679,379,280,776 is 10293640.
Find LCM of 679,379,280,776 with Prime Factorization
| 2 | 679, 379, 280, 776 |
| 2 | 679, 379, 140, 388 |
| 2 | 679, 379, 70, 194 |
| 7 | 679, 379, 35, 97 |
| 97 | 97, 379, 5, 97 |
| 1, 379, 5, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 7 x 97 x 1 x 379 x 5 x 1 = 10293640
Therefore, the lowest common multiple of 679,379,280,776 is 10293640.
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.
679 x 379 x 280 x 776 = 55915052480
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.
679 : 1, 7, 97, 679
379 : 1, 379
280 : 1, 2, 4, 5, 7, 8, 10, 14, 20, 28, 35, 40, 56, 70, 140, 280
776 : 1, 2, 4, 8, 97, 194, 388, 776
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 679,379,280,776, is 1.
Now, the common factors can be found like this.
679:7x 97
379:379
280:2x 2x 2x 5x 7
776:2x 2x 2x 97
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 2x 7x 97 = 5432
Therefore, the value for common factors is 5432.
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 = 55915052480/(1x5432)
LCM = 55915052480/5432
LCM = 10293640
Thus, we can understand that the LCM of 679,379,280,776 is 10293640.
