HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 471, 844, 161 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 471, 844, 161 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 471, 844, 161 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 471, 844, 161 is 1.

HCF(471, 844, 161) = 1

Highest common factor (HCF) of 471, 844, 161 is 1.

Highest Common Factor of 471,844,161 using Euclid's algorithm

Highest Common Factor of 471,844,161 is 1

Step 1: Since 844 > 471, we apply the division lemma to 844 and 471, to get

844 = 471 x 1 + 373

Step 2: Since the reminder 471 ≠ 0, we apply division lemma to 373 and 471, to get

471 = 373 x 1 + 98

Step 3: We consider the new divisor 373 and the new remainder 98, and apply the division lemma to get

373 = 98 x 3 + 79

We consider the new divisor 98 and the new remainder 79,and apply the division lemma to get

98 = 79 x 1 + 19

We consider the new divisor 79 and the new remainder 19,and apply the division lemma to get

79 = 19 x 4 + 3

We consider the new divisor 19 and the new remainder 3,and apply the division lemma to get

19 = 3 x 6 + 1

We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get

3 = 1 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 471 and 844 is 1

Notice that 1 = HCF(3,1) = HCF(19,3) = HCF(79,19) = HCF(98,79) = HCF(373,98) = HCF(471,373) = HCF(844,471) .

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

Step 1: Since 161 > 1, we apply the division lemma to 161 and 1, to get

161 = 1 x 161 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 161 is 1

Notice that 1 = HCF(161,1) .
