HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 770, 443 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 770, 443 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 770, 443 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 770, 443 is 1.

HCF(770, 443) = 1

Highest common factor (HCF) of 770, 443 is 1.

Highest Common Factor of 770,443 using Euclid's algorithm

Highest Common Factor of 770,443 is 1

Step 1: Since 770 > 443, we apply the division lemma to 770 and 443, to get

770 = 443 x 1 + 327

Step 2: Since the reminder 443 ≠ 0, we apply division lemma to 327 and 443, to get

443 = 327 x 1 + 116

Step 3: We consider the new divisor 327 and the new remainder 116, and apply the division lemma to get

327 = 116 x 2 + 95

We consider the new divisor 116 and the new remainder 95,and apply the division lemma to get

116 = 95 x 1 + 21

We consider the new divisor 95 and the new remainder 21,and apply the division lemma to get

95 = 21 x 4 + 11

We consider the new divisor 21 and the new remainder 11,and apply the division lemma to get

21 = 11 x 1 + 10

We consider the new divisor 11 and the new remainder 10,and apply the division lemma to get

11 = 10 x 1 + 1

We consider the new divisor 10 and the new remainder 1,and apply the division lemma to get

10 = 1 x 10 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 770 and 443 is 1

Notice that 1 = HCF(10,1) = HCF(11,10) = HCF(21,11) = HCF(95,21) = HCF(116,95) = HCF(327,116) = HCF(443,327) = HCF(770,443) .
