HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 76, 39, 78, 129 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 76, 39, 78, 129 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 76, 39, 78, 129 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 76, 39, 78, 129 is 1.

HCF(76, 39, 78, 129) = 1

HCF of 76, 39, 78, 129 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 76, 39, 78, 129 is 1.

Highest Common Factor of 76,39,78,129 using Euclid's algorithm

Highest Common Factor of 76,39,78,129 is 1

Step 1: Since 76 > 39, we apply the division lemma to 76 and 39, to get

76 = 39 x 1 + 37

Step 2: Since the reminder 39 ≠ 0, we apply division lemma to 37 and 39, to get

39 = 37 x 1 + 2

Step 3: We consider the new divisor 37 and the new remainder 2, and apply the division lemma to get

37 = 2 x 18 + 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 76 and 39 is 1

Notice that 1 = HCF(2,1) = HCF(37,2) = HCF(39,37) = HCF(76,39) .


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

Step 1: Since 78 > 1, we apply the division lemma to 78 and 1, to get

78 = 1 x 78 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 78 is 1

Notice that 1 = HCF(78,1) .


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

Step 1: Since 129 > 1, we apply the division lemma to 129 and 1, to get

129 = 1 x 129 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 129 is 1

Notice that 1 = HCF(129,1) .
