HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 694, 971, 193 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 694, 971, 193 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 694, 971, 193 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 694, 971, 193 is 1.

HCF(694, 971, 193) = 1

Highest common factor (HCF) of 694, 971, 193 is 1.

Highest Common Factor of 694,971,193 using Euclid's algorithm

Highest Common Factor of 694,971,193 is 1

Step 1: Since 971 > 694, we apply the division lemma to 971 and 694, to get

971 = 694 x 1 + 277

Step 2: Since the reminder 694 ≠ 0, we apply division lemma to 277 and 694, to get

694 = 277 x 2 + 140

Step 3: We consider the new divisor 277 and the new remainder 140, and apply the division lemma to get

277 = 140 x 1 + 137

We consider the new divisor 140 and the new remainder 137,and apply the division lemma to get

140 = 137 x 1 + 3

We consider the new divisor 137 and the new remainder 3,and apply the division lemma to get

137 = 3 x 45 + 2

We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get

3 = 2 x 1 + 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 694 and 971 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(137,3) = HCF(140,137) = HCF(277,140) = HCF(694,277) = HCF(971,694) .

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

Step 1: Since 193 > 1, we apply the division lemma to 193 and 1, to get

193 = 1 x 193 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 193 is 1

Notice that 1 = HCF(193,1) .
