Given numbers are 770,568,868,912
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 770,568,868,912 is 772815120.
Find LCM of 770,568,868,912 with Prime Factorization
| 2 | 770, 568, 868, 912 |
| 2 | 385, 284, 434, 456 |
| 2 | 385, 142, 217, 228 |
| 7 | 385, 71, 217, 114 |
| 55, 71, 31, 114 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 7 x 55 x 71 x 31 x 114 = 772815120
Therefore, the lowest common multiple of 770,568,868,912 is 772815120.
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.
770 x 568 x 868 x 912 = 346221173760
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.
770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770
568 : 1, 2, 4, 8, 71, 142, 284, 568
868 : 1, 2, 4, 7, 14, 28, 31, 62, 124, 217, 434, 868
912 : 1, 2, 3, 4, 6, 8, 12, 16, 19, 24, 38, 48, 57, 76, 114, 152, 228, 304, 456, 912
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 770,568,868,912, is 2.
Now, the common factors can be found like this.
770:2x 5x 7x 11
568:2x 2x 2x 71
868:2x 2x 7x 31
912:2x 2x 2x 2x 3x 19
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 7 = 224
Therefore, the value for common factors is 224.
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 = 346221173760/(2x224)
LCM = 346221173760/448
LCM = 772815120
Thus, we can understand that the LCM of 770,568,868,912 is 772815120.
