Find LCM of 868,976,620,766,188 with Prime Factorization
2 | 868, 976, 620, 766, 188 |
2 | 434, 488, 310, 383, 94 |
31 | 217, 244, 155, 383, 47 |
7, 244, 5, 383, 47 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 31 x 7 x 244 x 5 x 383 x 47 = 19062338960
Therefore, the lowest common multiple of 868,976,620,766,188 is 19062338960.
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.
868 x 976 x 620 x 766 x 188 = 75639360993280
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.
868 : 1, 2, 4, 7, 14, 28, 31, 62, 124, 217, 434, 868
976 : 1, 2, 4, 8, 16, 61, 122, 244, 488, 976
620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620
766 : 1, 2, 383, 766
188 : 1, 2, 4, 47, 94, 188
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 868,976,620,766,188, is 2.
Now, the common factors can be found like this.
868:2x 2x 7x 31
976:2x 2x 2x 2x 61
620:2x 2x 5x 31
766:2x 383
188:2x 2x 47
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 2x 2x 2x 31 = 1984
Therefore, the value for common factors is 1984.
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 = 75639360993280/(2x1984)
LCM = 75639360993280/3968
LCM = 19062338960
Thus, we can understand that the LCM of 868,976,620,766,188 is 19062338960.
