Given numbers are 413,649,615,761,978
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 413,649,615,761,978 is 693138639270.
Find LCM of 413,649,615,761,978 with Prime Factorization
| 3 | 413, 649, 615, 761, 978 |
| 59 | 413, 649, 205, 761, 326 |
| 7, 11, 205, 761, 326 |
Multiply the prime numbers at the bottom and the left side.
3 x 59 x 7 x 11 x 205 x 761 x 326 = 693138639270
Therefore, the lowest common multiple of 413,649,615,761,978 is 693138639270.
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.
413 x 649 x 615 x 761 x 978 = 122685539150790
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.
413 : 1, 7, 59, 413
649 : 1, 11, 59, 649
615 : 1, 3, 5, 15, 41, 123, 205, 615
761 : 1, 761
978 : 1, 2, 3, 6, 163, 326, 489, 978
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 413,649,615,761,978, is 1.
Now, the common factors can be found like this.
413:7x 59
649:11x 59
615:3x 5x 41
761:761
978:2x 3x 163
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 59 = 177
Therefore, the value for common factors is 177.
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 = 122685539150790/(1x177)
LCM = 122685539150790/177
LCM = 693138639270
Thus, we can understand that the LCM of 413,649,615,761,978 is 693138639270.
