HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 544, 965 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 544, 965 is 1 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 544, 965 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 544, 965 is 1.

HCF(544, 965) = 1

Highest common factor (HCF) of 544, 965 is 1.

Highest Common Factor of 544,965 using Euclid's algorithm

Highest Common Factor of 544,965 is 1

Step 1: Since 965 > 544, we apply the division lemma to 965 and 544, to get

965 = 544 x 1 + 421

Step 2: Since the reminder 544 ≠ 0, we apply division lemma to 421 and 544, to get

544 = 421 x 1 + 123

Step 3: We consider the new divisor 421 and the new remainder 123, and apply the division lemma to get

421 = 123 x 3 + 52

We consider the new divisor 123 and the new remainder 52,and apply the division lemma to get

123 = 52 x 2 + 19

We consider the new divisor 52 and the new remainder 19,and apply the division lemma to get

52 = 19 x 2 + 14

We consider the new divisor 19 and the new remainder 14,and apply the division lemma to get

19 = 14 x 1 + 5

We consider the new divisor 14 and the new remainder 5,and apply the division lemma to get

14 = 5 x 2 + 4

We consider the new divisor 5 and the new remainder 4,and apply the division lemma to get

5 = 4 x 1 + 1

We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get

4 = 1 x 4 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 544 and 965 is 1

Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(14,5) = HCF(19,14) = HCF(52,19) = HCF(123,52) = HCF(421,123) = HCF(544,421) = HCF(965,544) .
