HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 754, 443 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 754, 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 754, 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 754, 443 is 1.

HCF(754, 443) = 1

Highest common factor (HCF) of 754, 443 is 1.

Highest Common Factor of 754,443 using Euclid's algorithm

Highest Common Factor of 754,443 is 1

Step 1: Since 754 > 443, we apply the division lemma to 754 and 443, to get

754 = 443 x 1 + 311

Step 2: Since the reminder 443 ≠ 0, we apply division lemma to 311 and 443, to get

443 = 311 x 1 + 132

Step 3: We consider the new divisor 311 and the new remainder 132, and apply the division lemma to get

311 = 132 x 2 + 47

We consider the new divisor 132 and the new remainder 47,and apply the division lemma to get

132 = 47 x 2 + 38

We consider the new divisor 47 and the new remainder 38,and apply the division lemma to get

47 = 38 x 1 + 9

We consider the new divisor 38 and the new remainder 9,and apply the division lemma to get

38 = 9 x 4 + 2

We consider the new divisor 9 and the new remainder 2,and apply the division lemma to get

9 = 2 x 4 + 1

We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get

2 = 1 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 754 and 443 is 1

Notice that 1 = HCF(2,1) = HCF(9,2) = HCF(38,9) = HCF(47,38) = HCF(132,47) = HCF(311,132) = HCF(443,311) = HCF(754,443) .
