Find LCM of 945,987,770,496 with Prime Factorization
| 2 | 945, 987, 770, 496 |
| 3 | 945, 987, 385, 248 |
| 5 | 315, 329, 385, 248 |
| 7 | 63, 329, 77, 248 |
| 9, 47, 11, 248 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 7 x 9 x 47 x 11 x 248 = 242328240
Therefore, the lowest common multiple of 945,987,770,496 is 242328240.
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.
945 x 987 x 770 x 496 = 356222512800
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.
945 : 1, 3, 5, 7, 9, 15, 21, 27, 35, 45, 63, 105, 135, 189, 315, 945
987 : 1, 3, 7, 21, 47, 141, 329, 987
770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770
496 : 1, 2, 4, 8, 16, 31, 62, 124, 248, 496
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 945,987,770,496, is 1.
Now, the common factors can be found like this.
945:3x 3x 3x 5x 7
987:3x 7x 47
770:2x 5x 7x 11
496:2x 2x 2x 2x 31
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 5x 7x 7 = 1470
Therefore, the value for common factors is 1470.
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 = 356222512800/(1x1470)
LCM = 356222512800/1470
LCM = 242328240
Thus, we can understand that the LCM of 945,987,770,496 is 242328240.
