HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 829, 334, 78 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 829, 334, 78 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 829, 334, 78 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 829, 334, 78 is 1.

HCF(829, 334, 78) = 1

Highest Common Factor of 829,334,78 using Euclid's algorithm

Highest Common Factor of 829,334,78 is 1

Step 1: Since 829 > 334, we apply the division lemma to 829 and 334, to get

829 = 334 x 2 + 161

Step 2: Since the reminder 334 ≠ 0, we apply division lemma to 161 and 334, to get

334 = 161 x 2 + 12

Step 3: We consider the new divisor 161 and the new remainder 12, and apply the division lemma to get

161 = 12 x 13 + 5

We consider the new divisor 12 and the new remainder 5,and apply the division lemma to get

12 = 5 x 2 + 2

We consider the new divisor 5 and the new remainder 2,and apply the division lemma to get

5 = 2 x 2 + 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 829 and 334 is 1

Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(12,5) = HCF(161,12) = HCF(334,161) = HCF(829,334) .

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) .
