HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 823, 643, 952 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 823, 643, 952 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 823, 643, 952 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 823, 643, 952 is 1.

HCF(823, 643, 952) = 1

Highest common factor (HCF) of 823, 643, 952 is 1.

Highest Common Factor of 823,643,952 using Euclid's algorithm

Highest Common Factor of 823,643,952 is 1

Step 1: Since 823 > 643, we apply the division lemma to 823 and 643, to get

823 = 643 x 1 + 180

Step 2: Since the reminder 643 ≠ 0, we apply division lemma to 180 and 643, to get

643 = 180 x 3 + 103

Step 3: We consider the new divisor 180 and the new remainder 103, and apply the division lemma to get

180 = 103 x 1 + 77

We consider the new divisor 103 and the new remainder 77,and apply the division lemma to get

103 = 77 x 1 + 26

We consider the new divisor 77 and the new remainder 26,and apply the division lemma to get

77 = 26 x 2 + 25

We consider the new divisor 26 and the new remainder 25,and apply the division lemma to get

26 = 25 x 1 + 1

We consider the new divisor 25 and the new remainder 1,and apply the division lemma to get

25 = 1 x 25 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 823 and 643 is 1

Notice that 1 = HCF(25,1) = HCF(26,25) = HCF(77,26) = HCF(103,77) = HCF(180,103) = HCF(643,180) = HCF(823,643) .

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

Step 1: Since 952 > 1, we apply the division lemma to 952 and 1, to get

952 = 1 x 952 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 952 is 1

Notice that 1 = HCF(952,1) .
