HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 208, 789, 135 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 208, 789, 135 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 208, 789, 135 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 208, 789, 135 is 1.

HCF(208, 789, 135) = 1

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

HCF of:

Highest common factor (HCF) of 208, 789, 135 is 1.

Highest Common Factor of 208,789,135 using Euclid's algorithm

Highest Common Factor of 208,789,135 is 1

Step 1: Since 789 > 208, we apply the division lemma to 789 and 208, to get

789 = 208 x 3 + 165

Step 2: Since the reminder 208 ≠ 0, we apply division lemma to 165 and 208, to get

208 = 165 x 1 + 43

Step 3: We consider the new divisor 165 and the new remainder 43, and apply the division lemma to get

165 = 43 x 3 + 36

We consider the new divisor 43 and the new remainder 36,and apply the division lemma to get

43 = 36 x 1 + 7

We consider the new divisor 36 and the new remainder 7,and apply the division lemma to get

36 = 7 x 5 + 1

We consider the new divisor 7 and the new remainder 1,and apply the division lemma to get

7 = 1 x 7 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 208 and 789 is 1

Notice that 1 = HCF(7,1) = HCF(36,7) = HCF(43,36) = HCF(165,43) = HCF(208,165) = HCF(789,208) .

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

Step 1: Since 135 > 1, we apply the division lemma to 135 and 1, to get

135 = 1 x 135 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 135 is 1

Notice that 1 = HCF(135,1) .
