HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 43, 93, 29, 85 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 43, 93, 29, 85 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 43, 93, 29, 85 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 43, 93, 29, 85 is 1.

HCF(43, 93, 29, 85) = 1

HCF of 43, 93, 29, 85 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 43, 93, 29, 85 is 1.

Highest Common Factor of 43,93,29,85 using Euclid's algorithm

Highest Common Factor of 43,93,29,85 is 1

Step 1: Since 93 > 43, we apply the division lemma to 93 and 43, to get

93 = 43 x 2 + 7

Step 2: Since the reminder 43 ≠ 0, we apply division lemma to 7 and 43, to get

43 = 7 x 6 + 1

Step 3: We consider the new divisor 7 and the new remainder 1, and apply the division lemma to get

7 = 1 x 7 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 43 and 93 is 1

Notice that 1 = HCF(7,1) = HCF(43,7) = HCF(93,43) .


We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma

Step 1: Since 29 > 1, we apply the division lemma to 29 and 1, to get

29 = 1 x 29 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 29 is 1

Notice that 1 = HCF(29,1) .


We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma

Step 1: Since 85 > 1, we apply the division lemma to 85 and 1, to get

85 = 1 x 85 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 85 is 1

Notice that 1 = HCF(85,1) .
