The highest common factor is the greatest number which both numbers can divide by evenly. In this case, the greatest number 40 can divide by is 40. 80 can also divide by 40, and so this is a common factor. As no numbers greater than 40 will be able to divide 40 evenly, the hcf of 40 and 80 is 40.
The HCF of 4 and 90 is 2.
The HCF of 40 & 12 is... 4
The hcf of 45 and 40 is 5.
HCF(40, 63) = 1

The Greatest Common Factor of 80, 85, 90: 5
The highest common factor is the greatest number which both numbers can divide by evenly. In this case, the greatest number 40 can divide by is 40. 80 can also divide by 40, and so this is a common factor. As no numbers greater than 40 will be able to divide 40 evenly, the hcf of 40 and 80 is 40.
The HCF of 4 and 90 is 2.
2 x 2 x 2 x 5 ---- 40
85
The Highest Common Factor (HCF) of 35 and 80 is the largest number that divides both 35 and 80 without leaving a remainder. To find the HCF, you can use the Euclidean algorithm, which involves dividing the larger number by the smaller number and then dividing the divisor by the remainder until the remainder is zero. The HCF of 35 and 80 is 5.
The GCF is 10.
The HCF of 40 & 12 is... 4
The hcf of 45 and 40 is 5.
HCF(40, 63) = 1
The GCF is 18.
