Given numbers are 322,772,637,921,978
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 322,772,637,921,978 is 1697977000356.
Find LCM of 322,772,637,921,978 with Prime Factorization
2 | 322, 772, 637, 921, 978 |
3 | 161, 386, 637, 921, 489 |
7 | 161, 386, 637, 307, 163 |
23, 386, 91, 307, 163 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 23 x 386 x 91 x 307 x 163 = 1697977000356
Therefore, the lowest common multiple of 322,772,637,921,978 is 1697977000356.
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.
322 x 772 x 637 x 921 x 978 = 142630068029904
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.
322 : 1, 2, 7, 14, 23, 46, 161, 322
772 : 1, 2, 4, 193, 386, 772
637 : 1, 7, 13, 49, 91, 637
921 : 1, 3, 307, 921
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 322,772,637,921,978, is 1.
Now, the common factors can be found like this.
322:2x 7x 23
772:2x 2x 193
637:7x 7x 13
921:3x 307
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.
2x 2x 3x 7 = 84
Therefore, the value for common factors is 84.
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 = 142630068029904/(1x84)
LCM = 142630068029904/84
LCM = 1697977000356
Thus, we can understand that the LCM of 322,772,637,921,978 is 1697977000356.
