HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 729, 967, 842 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 729, 967, 842 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 729, 967, 842 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 729, 967, 842 is 1.

HCF(729, 967, 842) = 1

Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.

HCF of:

Highest common factor (HCF) of 729, 967, 842 is 1.

Highest Common Factor of 729,967,842 using Euclid's algorithm

Highest Common Factor of 729,967,842 is 1

Step 1: Since 967 > 729, we apply the division lemma to 967 and 729, to get

967 = 729 x 1 + 238

Step 2: Since the reminder 729 ≠ 0, we apply division lemma to 238 and 729, to get

729 = 238 x 3 + 15

Step 3: We consider the new divisor 238 and the new remainder 15, and apply the division lemma to get

238 = 15 x 15 + 13

We consider the new divisor 15 and the new remainder 13,and apply the division lemma to get

15 = 13 x 1 + 2

We consider the new divisor 13 and the new remainder 2,and apply the division lemma to get

13 = 2 x 6 + 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 729 and 967 is 1

Notice that 1 = HCF(2,1) = HCF(13,2) = HCF(15,13) = HCF(238,15) = HCF(729,238) = HCF(967,729) .

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

Step 1: Since 842 > 1, we apply the division lemma to 842 and 1, to get

842 = 1 x 842 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 842 is 1

Notice that 1 = HCF(842,1) .
