The prime factors of 30 are 2, 3 and 5.

The prime factors of 6 are [blank_start]2, 3[blank_end]. The prime factors of 12 are [blank_start]2,2,3[blank_end]. Therefore the highest common factor of both 6 and 12 is [blank_start]6[blank_end]. And the lowest common multiple is [blank_start]12[blank_end].

What is the highest common factor of 12 and 15?

The lowest common multiple of 6 and 8 is 25

What is the square of 16?

The cube of 5 is 25.

The square of 1 is [blank_start]1[blank_end]. The square of 2 is [blank_start]4[blank_end]. The square of 3 is [blank_start]9[blank_end]. The square of 4 is [blank_start]16[blank_end]. The square of 5 is [blank_start]25[blank_end]. The square of 6 is [blank_start]36[blank_end]. the square of 7 is [blank_start]49[blank_end]. The square of 8 is [blank_start]64[blank_end]. The square of 9 is [blank_start]81[blank_end]. The square of 10 is 100. The square of 11 is [blank_start]121[blank_end]. the square of 12 is [blank_start]144[blank_end]. When squares are [blank_start]negative[blank_end] they answer is positive because a negative times a negative equals a positive.
