HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 774, 765 i.e. 9 the largest integer that leaves a remainder zero for all numbers.

HCF of 774, 765 is 9 the largest number which exactly divides all the numbers i.e. where the remainder is zero. Let us get into the working of this example.

Consider we have numbers 774, 765 and we need to find the HCF of these numbers. To do so, we need to choose the largest integer first and then as per Euclid's Division Lemma a = bq + r where 0 ≤ r ≤ b

Highest common factor (HCF) of 774, 765 is 9.

HCF(774, 765) = 9

HCF of 774, 765 using Euclid's algorithm

Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.

HCF of:

Highest common factor (HCF) of 774, 765 is 9.

Highest Common Factor of 774,765 using Euclid's algorithm

Highest Common Factor of 774,765 is 9

Step 1: Since 774 > 765, we apply the division lemma to 774 and 765, to get

774 = 765 x 1 + 9

Step 2: Since the reminder 765 ≠ 0, we apply division lemma to 9 and 765, to get

765 = 9 x 85 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 9, the HCF of 774 and 765 is 9

Notice that 9 = HCF(765,9) = HCF(774,765) .
