HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 788, 91 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 788, 91 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 788, 91 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 788, 91 is 1.

HCF(788, 91) = 1

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

HCF of:

Highest common factor (HCF) of 788, 91 is 1.

Highest Common Factor of 788,91 using Euclid's algorithm

Highest Common Factor of 788,91 is 1

Step 1: Since 788 > 91, we apply the division lemma to 788 and 91, to get

788 = 91 x 8 + 60

Step 2: Since the reminder 91 ≠ 0, we apply division lemma to 60 and 91, to get

91 = 60 x 1 + 31

Step 3: We consider the new divisor 60 and the new remainder 31, and apply the division lemma to get

60 = 31 x 1 + 29

We consider the new divisor 31 and the new remainder 29,and apply the division lemma to get

31 = 29 x 1 + 2

We consider the new divisor 29 and the new remainder 2,and apply the division lemma to get

29 = 2 x 14 + 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 788 and 91 is 1

Notice that 1 = HCF(2,1) = HCF(29,2) = HCF(31,29) = HCF(60,31) = HCF(91,60) = HCF(788,91) .
