Yes because 7.8 you count the numbers that are not complied with 70.08 get it if not ask again and i'll explain more:)
2 and 78. 2*78=156
2 of them.
It is: 2*3*13 = 78
The median of 2 numbers is the same as their mean, which is (69 + 78)/2 = 73.5
I assume you mean prime factors. 78 = 2*3*13
1/2 (78 + 88) = 83
They are: 2*3*13 = 78
It's not. 78 is the LCM of those numbers. The GCF of those numbers is 1.
78 6 x 13 (2x3) x 13 The numbers 2, 3, and 13 are prime numbers, so the factor tree is complete. An alternate version of a factor tree for 78 is: 78 2 x 39 2 x (3x13)
All even numbers greater than 2 are composite numbers

1 and 2.
