3 x 6 = 18, 5 x 6 = 30; six is the largest common factor.
10 is the largest common factor
Factor 18 and y then look for the largest common factor form both sets of factors. For example, the factors of 18 are 2,3,6,9,18 if y = 30, then its factors are 2,3,5,6,10,15,30 So the greatest common factor is 6
The Highest Common Factor (HCF) of 18 and 30 is the largest positive integer that divides both numbers without leaving a remainder. To find the HCF, we need to determine the common factors of 18 (1, 2, 3, 6, 9, 18) and 30 (1, 2, 3, 5, 6, 10, 15, 30) and identify the largest one they share, which is 6. Therefore, the HCF of 18 and 30 is 6.
Since 30 is a factor of 60, and the largest possible factor of 30 is 30, the greatest common factor is 30.
The Greatest Common Factor of 18, 27, and 30 is 3.
The Greatest Common Factor of 18, 24, 30: 6

15
The greatest common factor of the numbers 18, 30 and 72 is 6.
The GCF is 3.
