HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 681, 192 i.e. 3 the largest integer that leaves a remainder zero for all numbers.

HCF of 681, 192 is 3 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 681, 192 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 681, 192 is 3.

HCF(681, 192) = 3

Highest common factor (HCF) of 681, 192 is 3.

Highest Common Factor of 681,192 using Euclid's algorithm

Highest Common Factor of 681,192 is 3

Step 1: Since 681 > 192, we apply the division lemma to 681 and 192, to get

681 = 192 x 3 + 105

Step 2: Since the reminder 192 ≠ 0, we apply division lemma to 105 and 192, to get

192 = 105 x 1 + 87

Step 3: We consider the new divisor 105 and the new remainder 87, and apply the division lemma to get

105 = 87 x 1 + 18

We consider the new divisor 87 and the new remainder 18,and apply the division lemma to get

87 = 18 x 4 + 15

We consider the new divisor 18 and the new remainder 15,and apply the division lemma to get

18 = 15 x 1 + 3

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

15 = 3 x 5 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 681 and 192 is 3

Notice that 3 = HCF(15,3) = HCF(18,15) = HCF(87,18) = HCF(105,87) = HCF(192,105) = HCF(681,192) .
