HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 324, 202, 968 i.e. 2 the largest integer that leaves a remainder zero for all numbers.

HCF of 324, 202, 968 is 2 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 324, 202, 968 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 324, 202, 968 is 2.

HCF(324, 202, 968) = 2

Highest Common Factor of 324,202,968 using Euclid's algorithm

Highest Common Factor of 324,202,968 is 2

Step 1: Since 324 > 202, we apply the division lemma to 324 and 202, to get

324 = 202 x 1 + 122

Step 2: Since the reminder 202 ≠ 0, we apply division lemma to 122 and 202, to get

202 = 122 x 1 + 80

Step 3: We consider the new divisor 122 and the new remainder 80, and apply the division lemma to get

122 = 80 x 1 + 42

We consider the new divisor 80 and the new remainder 42,and apply the division lemma to get

80 = 42 x 1 + 38

We consider the new divisor 42 and the new remainder 38,and apply the division lemma to get

42 = 38 x 1 + 4

We consider the new divisor 38 and the new remainder 4,and apply the division lemma to get

38 = 4 x 9 + 2

We consider the new divisor 4 and the new remainder 2,and apply the division lemma to get

4 = 2 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 324 and 202 is 2

Notice that 2 = HCF(4,2) = HCF(38,4) = HCF(42,38) = HCF(80,42) = HCF(122,80) = HCF(202,122) = HCF(324,202) .

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

Step 1: Since 968 > 2, we apply the division lemma to 968 and 2, to get

968 = 2 x 484 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 968 is 2

Notice that 2 = HCF(968,2) .
