Given numbers are 222,772,990,770
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 222,772,990,770 is 98974260.
Find LCM of 222,772,990,770 with Prime Factorization
| 2 | 222, 772, 990, 770 |
| 3 | 111, 386, 495, 385 |
| 5 | 37, 386, 165, 385 |
| 11 | 37, 386, 33, 77 |
| 37, 386, 3, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 11 x 37 x 386 x 3 x 7 = 98974260
Therefore, the lowest common multiple of 222,772,990,770 is 98974260.
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.
222 x 772 x 990 x 770 = 130646023200
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.
222 : 1, 2, 3, 6, 37, 74, 111, 222
772 : 1, 2, 4, 193, 386, 772
990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990
770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 222,772,990,770, is 2.
Now, the common factors can be found like this.
222:2x 3x 37
772:2x 2x 193
990:2x 3x 3x 5x 11
770:2x 5x 7x 11
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 5x 11 = 660
Therefore, the value for common factors is 660.
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 = 130646023200/(2x660)
LCM = 130646023200/1320
LCM = 98974260
Thus, we can understand that the LCM of 222,772,990,770 is 98974260.
