Since âˆ’35x3,15x4 - 35 x 3 , 15 x 4 contain both numbers and variables, there are two steps to find the GCF (HCF). Find GCF for the numeric part then find GCF for the variable part.
The GCF of 30 x^2 and 45x is 15x. The GCF of 30 and 45 is 15, and the GCF of x squared and x is x.
The GCF is 15x^2y^2
gcf(35x², 7xy², 21x²y²) = 7x 35x² = 5 times 7 times x² 7xy² = 7 times x times y² 21x²y² = 3 times 7 times x² times y² hcf = 7 times x = 7x (I've written the multiplication as times instead of using the × symbol to avoid confusion with the unknown x.)
-15x=-5*3x+2 -15x=-15x+2 +15x +15x ----------------- 0=2
The GCF is 2^2.
5x^3(3x + 2)
-x - 2 + 15x = 14x - 2
The GCF is 8rs.
The GCF is 13x
The GCF is 1.
6/5x = 18/15x 2/3x = 10/15x 18/15x - 10/15x = 8/15x
