HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 328, 648, 316, 66 i.e. 2 the largest integer that leaves a remainder zero for all numbers.

HCF of 328, 648, 316, 66 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 328, 648, 316, 66 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 328, 648, 316, 66 is 2.

HCF(328, 648, 316, 66) = 2

Highest common factor (HCF) of 328, 648, 316, 66 is 2.

Highest Common Factor of 328,648,316,66 using Euclid's algorithm

Highest Common Factor of 328,648,316,66 is 2

Step 1: Since 648 > 328, we apply the division lemma to 648 and 328, to get

648 = 328 x 1 + 320

Step 2: Since the reminder 328 ≠ 0, we apply division lemma to 320 and 328, to get

328 = 320 x 1 + 8

Step 3: We consider the new divisor 320 and the new remainder 8, and apply the division lemma to get

320 = 8 x 40 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 8, the HCF of 328 and 648 is 8

Notice that 8 = HCF(320,8) = HCF(328,320) = HCF(648,328) .


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

Step 1: Since 316 > 8, we apply the division lemma to 316 and 8, to get

316 = 8 x 39 + 4

Step 2: Since the reminder 8 ≠ 0, we apply division lemma to 4 and 8, to get

8 = 4 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 8 and 316 is 4

Notice that 4 = HCF(8,4) = HCF(316,8) .


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

Step 1: Since 66 > 4, we apply the division lemma to 66 and 4, to get

66 = 4 x 16 + 2

Step 2: Since the reminder 4 ≠ 0, we apply division lemma to 2 and 4, 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 4 and 66 is 2

Notice that 2 = HCF(4,2) = HCF(66,4) .
