HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 622, 861, 170 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 622, 861, 170 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 622, 861, 170 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 622, 861, 170 is 1.

HCF(622, 861, 170) = 1

HCF of 622, 861, 170 using Euclid's algorithm

Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.

HCF of:

Highest common factor (HCF) of 622, 861, 170 is 1.

Highest Common Factor of 622,861,170 using Euclid's algorithm

Highest Common Factor of 622,861,170 is 1

Step 1: Since 861 > 622, we apply the division lemma to 861 and 622, to get

861 = 622 x 1 + 239

Step 2: Since the reminder 622 ≠ 0, we apply division lemma to 239 and 622, to get

622 = 239 x 2 + 144

Step 3: We consider the new divisor 239 and the new remainder 144, and apply the division lemma to get

239 = 144 x 1 + 95

We consider the new divisor 144 and the new remainder 95,and apply the division lemma to get

144 = 95 x 1 + 49

We consider the new divisor 95 and the new remainder 49,and apply the division lemma to get

95 = 49 x 1 + 46

We consider the new divisor 49 and the new remainder 46,and apply the division lemma to get

49 = 46 x 1 + 3

We consider the new divisor 46 and the new remainder 3,and apply the division lemma to get

46 = 3 x 15 + 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 622 and 861 is 1

Notice that 1 = HCF(3,1) = HCF(46,3) = HCF(49,46) = HCF(95,49) = HCF(144,95) = HCF(239,144) = HCF(622,239) = HCF(861,622) .


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

Step 1: Since 170 > 1, we apply the division lemma to 170 and 1, to get

170 = 1 x 170 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 170 is 1

Notice that 1 = HCF(170,1) .
