Given numbers are 619,693,802,978,802
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 619,693,802,978,802 is 56077140042.
Find LCM of 619,693,802,978,802 with Prime Factorization
| 2 | 619, 693, 802, 978, 802 |
| 3 | 619, 693, 401, 489, 401 |
| 401 | 619, 231, 401, 163, 401 |
| 619, 231, 1, 163, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 401 x 619 x 231 x 1 x 163 x 1 = 56077140042
Therefore, the lowest common multiple of 619,693,802,978,802 is 56077140042.
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.
619 x 693 x 802 x 978 x 802 = 269843197882104
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.
619 : 1, 619
693 : 1, 3, 7, 9, 11, 21, 33, 63, 77, 99, 231, 693
802 : 1, 2, 401, 802
978 : 1, 2, 3, 6, 163, 326, 489, 978
802 : 1, 2, 401, 802
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 619,693,802,978,802, is 1.
Now, the common factors can be found like this.
619:619
693:3x 3x 7x 11
802:2x 401
978:2x 3x 163
802:2x 401
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 3x 401 = 4812
Therefore, the value for common factors is 4812.
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 = 269843197882104/(1x4812)
LCM = 269843197882104/4812
LCM = 56077140042
Thus, we can understand that the LCM of 619,693,802,978,802 is 56077140042.
