HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 424, 823, 87 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 424, 823, 87 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 424, 823, 87 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 424, 823, 87 is 1.

HCF(424, 823, 87) = 1

Highest common factor (HCF) of 424, 823, 87 is 1.

Highest Common Factor of 424,823,87 using Euclid's algorithm

Highest Common Factor of 424,823,87 is 1

Step 1: Since 823 > 424, we apply the division lemma to 823 and 424, to get

823 = 424 x 1 + 399

Step 2: Since the reminder 424 ≠ 0, we apply division lemma to 399 and 424, to get

424 = 399 x 1 + 25

Step 3: We consider the new divisor 399 and the new remainder 25, and apply the division lemma to get

399 = 25 x 15 + 24

We consider the new divisor 25 and the new remainder 24,and apply the division lemma to get

25 = 24 x 1 + 1

We consider the new divisor 24 and the new remainder 1,and apply the division lemma to get

24 = 1 x 24 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 424 and 823 is 1

Notice that 1 = HCF(24,1) = HCF(25,24) = HCF(399,25) = HCF(424,399) = HCF(823,424) .


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

Step 1: Since 87 > 1, we apply the division lemma to 87 and 1, to get

87 = 1 x 87 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 87 is 1

Notice that 1 = HCF(87,1) .
