Since 18 is a factor of 810, it is automatically the GCF.
no
The greatest common factor of 100 , 810 = 10
1 to 5
15
The number 1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 81, 90, 135, 162, 270, 405, and 810 is a factor of 810.
the factor tree for 70 is 70 ^ 10X5 ^ 5X2 SO IT WOULD BE 52
81
The GCF is: 10
Their at the bottom of the tree because the hole point of a factor tree is to find the prime factorization of the number, so it would be at the bottom of the tree.
The answer to that would be 7x5x2=70
