HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 791, 960, 197 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 791, 960, 197 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 791, 960, 197 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 791, 960, 197 is 1.

HCF(791, 960, 197) = 1

Highest common factor (HCF) of 791, 960, 197 is 1.

Highest Common Factor of 791,960,197 using Euclid's algorithm

Highest Common Factor of 791,960,197 is 1

Step 1: Since 960 > 791, we apply the division lemma to 960 and 791, to get

960 = 791 x 1 + 169

Step 2: Since the reminder 791 ≠ 0, we apply division lemma to 169 and 791, to get

791 = 169 x 4 + 115

Step 3: We consider the new divisor 169 and the new remainder 115, and apply the division lemma to get

169 = 115 x 1 + 54

We consider the new divisor 115 and the new remainder 54,and apply the division lemma to get

115 = 54 x 2 + 7

We consider the new divisor 54 and the new remainder 7,and apply the division lemma to get

54 = 7 x 7 + 5

We consider the new divisor 7 and the new remainder 5,and apply the division lemma to get

7 = 5 x 1 + 2

We consider the new divisor 5 and the new remainder 2,and apply the division lemma to get

5 = 2 x 2 + 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 791 and 960 is 1

Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(7,5) = HCF(54,7) = HCF(115,54) = HCF(169,115) = HCF(791,169) = HCF(960,791) .

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

Step 1: Since 197 > 1, we apply the division lemma to 197 and 1, to get

197 = 1 x 197 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 197 is 1

Notice that 1 = HCF(197,1) .
