The LCM of 924,620,678,785 is 2540866020.
Find LCM of 924,620,678,785 with Prime Factorization
| 2 | 924, 620, 678, 785 |
| 2 | 462, 310, 339, 785 |
| 3 | 231, 155, 339, 785 |
| 5 | 77, 155, 113, 785 |
| 77, 31, 113, 157 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 77 x 31 x 113 x 157 = 2540866020
Therefore, the lowest common multiple of 924,620,678,785 is 2540866020.
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.
924 x 620 x 678 x 785 = 304903922400
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.
924 : 1, 2, 3, 4, 6, 7, 11, 12, 14, 21, 22, 28, 33, 42, 44, 66, 77, 84, 132, 154, 231, 308, 462, 924
620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620
678 : 1, 2, 3, 6, 113, 226, 339, 678
785 : 1, 5, 157, 785
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 924,620,678,785, is 1.
Now, the common factors can be found like this.
924:2x 2x 3x 7x 11
620:2x 2x 5x 31
678:2x 3x 113
785:5x 157
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 3x 5 = 120
Therefore, the value for common factors is 120.
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 = 304903922400/(1x120)
LCM = 304903922400/120
LCM = 2540866020
Thus, we can understand that the LCM of 924,620,678,785 is 2540866020.
