HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 339, 285, 657 i.e. 3 the largest integer that leaves a remainder zero for all numbers.

HCF of 339, 285, 657 is 3 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 339, 285, 657 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 339, 285, 657 is 3.

HCF(339, 285, 657) = 3

Highest common factor (HCF) of 339, 285, 657 is 3.

Highest Common Factor of 339,285,657 using Euclid's algorithm

Highest Common Factor of 339,285,657 is 3

Step 1: Since 339 > 285, we apply the division lemma to 339 and 285, to get

339 = 285 x 1 + 54

Step 2: Since the reminder 285 ≠ 0, we apply division lemma to 54 and 285, to get

285 = 54 x 5 + 15

Step 3: We consider the new divisor 54 and the new remainder 15, and apply the division lemma to get

54 = 15 x 3 + 9

We consider the new divisor 15 and the new remainder 9,and apply the division lemma to get

15 = 9 x 1 + 6

We consider the new divisor 9 and the new remainder 6,and apply the division lemma to get

9 = 6 x 1 + 3

We consider the new divisor 6 and the new remainder 3,and apply the division lemma to get

6 = 3 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 339 and 285 is 3

Notice that 3 = HCF(6,3) = HCF(9,6) = HCF(15,9) = HCF(54,15) = HCF(285,54) = HCF(339,285) .


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

Step 1: Since 657 > 3, we apply the division lemma to 657 and 3, to get

657 = 3 x 219 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 3 and 657 is 3

Notice that 3 = HCF(657,3) .
