Given numbers are 770,890,984,556,122
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 770,890,984,556,122 is 285884408040.
Find LCM of 770,890,984,556,122 with Prime Factorization
| 2 | 770, 890, 984, 556, 122 |
| 2 | 385, 445, 492, 278, 61 |
| 5 | 385, 445, 246, 139, 61 |
| 77, 89, 246, 139, 61 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 77 x 89 x 246 x 139 x 61 = 285884408040
Therefore, the lowest common multiple of 770,890,984,556,122 is 285884408040.
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 890 x 984 x 556 x 122 = 45741505286400
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
890 : 1, 2, 5, 10, 89, 178, 445, 890
984 : 1, 2, 3, 4, 6, 8, 12, 24, 41, 82, 123, 164, 246, 328, 492, 984
556 : 1, 2, 4, 139, 278, 556
122 : 1, 2, 61, 122
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 770,890,984,556,122, is 2.
Now, the common factors can be found like this.
770:2x 5x 7x 11
890:2x 5x 89
984:2x 2x 2x 3x 41
556:2x 2x 139
122:2x 61
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 5 = 80
Therefore, the value for common factors is 80.
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 = 45741505286400/(2x80)
LCM = 45741505286400/160
LCM = 285884408040
Thus, we can understand that the LCM of 770,890,984,556,122 is 285884408040.
