The LCM of 604,984,820,894,985 is 21806930760.
Find LCM of 604,984,820,894,985 with Prime Factorization
| 2 | 604, 984, 820, 894, 985 |
| 2 | 302, 492, 410, 447, 985 |
| 3 | 151, 246, 205, 447, 985 |
| 5 | 151, 82, 205, 149, 985 |
| 41 | 151, 82, 41, 149, 197 |
| 151, 2, 1, 149, 197 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 41 x 151 x 2 x 1 x 149 x 197 = 21806930760
Therefore, the lowest common multiple of 604,984,820,894,985 is 21806930760.
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.
604 x 984 x 820 x 894 x 985 = 429160397356800
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.
604 : 1, 2, 4, 151, 302, 604
984 : 1, 2, 3, 4, 6, 8, 12, 24, 41, 82, 123, 164, 246, 328, 492, 984
820 : 1, 2, 4, 5, 10, 20, 41, 82, 164, 205, 410, 820
894 : 1, 2, 3, 6, 149, 298, 447, 894
985 : 1, 5, 197, 985
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 604,984,820,894,985, is 1.
Now, the common factors can be found like this.
604:2x 2x 151
984:2x 2x 2x 3x 41
820:2x 2x 5x 41
894:2x 3x 149
985:5x 197
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 3x 5x 41 = 19680
Therefore, the value for common factors is 19680.
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 = 429160397356800/(1x19680)
LCM = 429160397356800/19680
LCM = 21806930760
Thus, we can understand that the LCM of 604,984,820,894,985 is 21806930760.
