HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 783, 203, 166 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 783, 203, 166 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 783, 203, 166 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 783, 203, 166 is 1.

HCF(783, 203, 166) = 1

HCF of 783, 203, 166 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 783, 203, 166 is 1.

Highest Common Factor of 783,203,166 using Euclid's algorithm

Highest Common Factor of 783,203,166 is 1

Step 1: Since 783 > 203, we apply the division lemma to 783 and 203, to get

783 = 203 x 3 + 174

Step 2: Since the reminder 203 ≠ 0, we apply division lemma to 174 and 203, to get

203 = 174 x 1 + 29

Step 3: We consider the new divisor 174 and the new remainder 29, and apply the division lemma to get

174 = 29 x 6 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 29, the HCF of 783 and 203 is 29

Notice that 29 = HCF(174,29) = HCF(203,174) = HCF(783,203) .


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

Step 1: Since 166 > 29, we apply the division lemma to 166 and 29, to get

166 = 29 x 5 + 21

Step 2: Since the reminder 29 ≠ 0, we apply division lemma to 21 and 29, to get

29 = 21 x 1 + 8

Step 3: We consider the new divisor 21 and the new remainder 8, and apply the division lemma to get

21 = 8 x 2 + 5

We consider the new divisor 8 and the new remainder 5,and apply the division lemma to get

8 = 5 x 1 + 3

We consider the new divisor 5 and the new remainder 3,and apply the division lemma to get

5 = 3 x 1 + 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 29 and 166 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(8,5) = HCF(21,8) = HCF(29,21) = HCF(166,29) .
