HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 774, 849 i.e. 3 the largest integer that leaves a remainder zero for all numbers.

HCF of 774, 849 is 3 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, 849 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, 849 is 3.

HCF(774, 849) = 3

HCF of 774, 849 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, 849 is 3.

Highest Common Factor of 774,849 using Euclid's algorithm

Highest Common Factor of 774,849 is 3

Step 1: Since 849 > 774, we apply the division lemma to 849 and 774, to get

849 = 774 x 1 + 75

Step 2: Since the reminder 774 ≠ 0, we apply division lemma to 75 and 774, to get

774 = 75 x 10 + 24

Step 3: We consider the new divisor 75 and the new remainder 24, and apply the division lemma to get

75 = 24 x 3 + 3

We consider the new divisor 24 and the new remainder 3, and apply the division lemma to get

24 = 3 x 8 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 774 and 849 is 3

Notice that 3 = HCF(24,3) = HCF(75,24) = HCF(774,75) = HCF(849,774) .
