HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 641, 808, 192 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 641, 808, 192 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 641, 808, 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 641, 808, 192 is 1.

HCF(641, 808, 192) = 1

Highest common factor (HCF) of 641, 808, 192 is 1.

Highest Common Factor of 641,808,192 using Euclid's algorithm

Highest Common Factor of 641,808,192 is 1

Step 1: Since 808 > 641, we apply the division lemma to 808 and 641, to get

808 = 641 x 1 + 167

Step 2: Since the reminder 641 ≠ 0, we apply division lemma to 167 and 641, to get

641 = 167 x 3 + 140

Step 3: We consider the new divisor 167 and the new remainder 140, and apply the division lemma to get

167 = 140 x 1 + 27

We consider the new divisor 140 and the new remainder 27,and apply the division lemma to get

140 = 27 x 5 + 5

We consider the new divisor 27 and the new remainder 5,and apply the division lemma to get

27 = 5 x 5 + 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 641 and 808 is 1

Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(27,5) = HCF(140,27) = HCF(167,140) = HCF(641,167) = HCF(808,641) .

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

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

192 = 1 x 192 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 192 is 1

Notice that 1 = HCF(192,1) .
