factors of 2025 - 1, 3, 5, 9, 25, 81, 225, 405, 675, 2025, the facotrs 9 and 81 addto 90
The GCF of 81 and 90 is 9. This leaves 9 and 10 after division respectively. This cannot be further simplified using other common factors
The GCF is 9.
100*81/90 = 90%
The factors of 81 are: 1, 3, 9, 27, 81The factors of 90 are: 1, 2, 3, 5, 6, 9, 10, 15, 18, 30, 45, 90The common factors are: 1, 3, 9
It is 90 because 90% of 90 = 81
The LCM is 810.
The GCF of 81 and 90 is: 9Definition: A factor is a divisor - a number that will evenly divide into another number. The greatest common factor of two or more numbers is the largest factor that the numbers have in common.Method:One way to determine the common factors and greatest common factor is to find all the factors of the numbers and compare them.The factors of 81 are 1, 3, 9, 27, and 81.The factors of 90 are 1, 2, 3, 5, 6, 9, 10, 15, 18, 30, 45, and 90.The common factors are 1, 3, and 9. Therefore, the greatest common factor is 9.
The factors of 81 are: 1, 3, 9, 27, 81The factors of 90 are: 1, 2, 3, 5, 6, 9, 10, 15, 18, 30, 45, 90The common factors are: 1, 3, 9The Greatest Common Factor (GCF) is: 9
"90 percent" means 0.9, and "of" in arithmetic usually means "times". 0.9 x 90 = 81. 90 percent of 90 is 81.
