HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 824, 364, 79 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 824, 364, 79 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 824, 364, 79 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 824, 364, 79 is 1.

HCF(824, 364, 79) = 1

Highest common factor (HCF) of 824, 364, 79 is 1.

Highest Common Factor of 824,364,79 using Euclid's algorithm

Highest Common Factor of 824,364,79 is 1

Step 1: Since 824 > 364, we apply the division lemma to 824 and 364, to get

824 = 364 x 2 + 96

Step 2: Since the reminder 364 ≠ 0, we apply division lemma to 96 and 364, to get

364 = 96 x 3 + 76

Step 3: We consider the new divisor 96 and the new remainder 76, and apply the division lemma to get

96 = 76 x 1 + 20

We consider the new divisor 76 and the new remainder 20,and apply the division lemma to get

76 = 20 x 3 + 16

We consider the new divisor 20 and the new remainder 16,and apply the division lemma to get

20 = 16 x 1 + 4

We consider the new divisor 16 and the new remainder 4,and apply the division lemma to get

16 = 4 x 4 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 824 and 364 is 4

Notice that 4 = HCF(16,4) = HCF(20,16) = HCF(76,20) = HCF(96,76) = HCF(364,96) = HCF(824,364) .


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

Step 1: Since 79 > 4, we apply the division lemma to 79 and 4, to get

79 = 4 x 19 + 3

Step 2: Since the reminder 4 ≠ 0, we apply division lemma to 3 and 4, to get

4 = 3 x 1 + 1

Step 3: We consider the new divisor 3 and the new remainder 1, and apply the division lemma to get

3 = 1 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 4 and 79 is 1

Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(79,4) .
