The LCM of 523,506,120,654,989 is 74421498360.
Find LCM of 523,506,120,654,989 with Prime Factorization
| 2 | 523, 506, 120, 654, 989 |
| 3 | 523, 253, 60, 327, 989 |
| 23 | 523, 253, 20, 109, 989 |
| 523, 11, 20, 109, 43 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 23 x 523 x 11 x 20 x 109 x 43 = 74421498360
Therefore, the lowest common multiple of 523,506,120,654,989 is 74421498360.
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.
523 x 506 x 120 x 654 x 989 = 20540333547360
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.
523 : 1, 523
506 : 1, 2, 11, 22, 23, 46, 253, 506
120 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, 120
654 : 1, 2, 3, 6, 109, 218, 327, 654
989 : 1, 23, 43, 989
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 523,506,120,654,989, is 1.
Now, the common factors can be found like this.
523:523
506:2x 11x 23
120:2x 2x 2x 3x 5
654:2x 3x 109
989:23x 43
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 23 = 276
Therefore, the value for common factors is 276.
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 = 20540333547360/(1x276)
LCM = 20540333547360/276
LCM = 74421498360
Thus, we can understand that the LCM of 523,506,120,654,989 is 74421498360.
