HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 782, 7191 i.e. 17 the largest integer that leaves a remainder zero for all numbers.

HCF of 782, 7191 is 17 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 782, 7191 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 782, 7191 is 17.

HCF(782, 7191) = 17

Highest common factor (HCF) of 782, 7191 is 17.

Highest Common Factor of 782,7191 using Euclid's algorithm

Highest Common Factor of 782,7191 is 17

Step 1: Since 7191 > 782, we apply the division lemma to 7191 and 782, to get

7191 = 782 x 9 + 153

Step 2: Since the reminder 782 ≠ 0, we apply division lemma to 153 and 782, to get

782 = 153 x 5 + 17

Step 3: We consider the new divisor 153 and the new remainder 17, and apply the division lemma to get

153 = 17 x 9 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 17, the HCF of 782 and 7191 is 17

Notice that 17 = HCF(153,17) = HCF(782,153) = HCF(7191,782) .
