HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 643, 308, 213, 884 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 643, 308, 213, 884 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 643, 308, 213, 884 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 643, 308, 213, 884 is 1.

HCF(643, 308, 213, 884) = 1

Highest common factor (HCF) of 643, 308, 213, 884 is 1.

Highest Common Factor of 643,308,213,884 using Euclid's algorithm

Highest Common Factor of 643,308,213,884 is 1

Step 1: Since 643 > 308, we apply the division lemma to 643 and 308, to get

643 = 308 x 2 + 27

Step 2: Since the reminder 308 ≠ 0, we apply division lemma to 27 and 308, to get

308 = 27 x 11 + 11

Step 3: We consider the new divisor 27 and the new remainder 11, and apply the division lemma to get

27 = 11 x 2 + 5

We consider the new divisor 11 and the new remainder 5,and apply the division lemma to get

11 = 5 x 2 + 1

We consider the new divisor 5 and the new remainder 1,and apply the division lemma to get

5 = 1 x 5 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 643 and 308 is 1

Notice that 1 = HCF(5,1) = HCF(11,5) = HCF(27,11) = HCF(308,27) = HCF(643,308) .


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

Step 1: Since 213 > 1, we apply the division lemma to 213 and 1, to get

213 = 1 x 213 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 213 is 1

Notice that 1 = HCF(213,1) .


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

Step 1: Since 884 > 1, we apply the division lemma to 884 and 1, to get

884 = 1 x 884 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 884 is 1

Notice that 1 = HCF(884,1) .
