HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 239, 636, 68 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 239, 636, 68 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 239, 636, 68 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 239, 636, 68 is 1.

HCF(239, 636, 68) = 1

Highest common factor (HCF) of 239, 636, 68 is 1.

Highest Common Factor of 239,636,68 using Euclid's algorithm

Highest Common Factor of 239,636,68 is 1

Step 1: Since 636 > 239, we apply the division lemma to 636 and 239, to get

636 = 239 x 2 + 158

Step 2: Since the reminder 239 ≠ 0, we apply division lemma to 158 and 239, to get

239 = 158 x 1 + 81

Step 3: We consider the new divisor 158 and the new remainder 81, and apply the division lemma to get

158 = 81 x 1 + 77

We consider the new divisor 81 and the new remainder 77,and apply the division lemma to get

81 = 77 x 1 + 4

We consider the new divisor 77 and the new remainder 4,and apply the division lemma to get

77 = 4 x 19 + 1

We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get

4 = 1 x 4 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 239 and 636 is 1

Notice that 1 = HCF(4,1) = HCF(77,4) = HCF(81,77) = HCF(158,81) = HCF(239,158) = HCF(636,239) .

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

Step 1: Since 68 > 1, we apply the division lemma to 68 and 1, to get

68 = 1 x 68 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 68 is 1

Notice that 1 = HCF(68,1) .
