HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 327, 858 i.e. 3 the largest integer that leaves a remainder zero for all numbers.

HCF of 327, 858 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 327, 858 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 327, 858 is 3.

HCF(327, 858) = 3

Highest common factor (HCF) of 327, 858 is 3.

Highest Common Factor of 327,858 using Euclid's algorithm

Highest Common Factor of 327,858 is 3

Step 1: Since 858 > 327, we apply the division lemma to 858 and 327, to get

858 = 327 x 2 + 204

Step 2: Since the reminder 327 ≠ 0, we apply division lemma to 204 and 327, to get

327 = 204 x 1 + 123

Step 3: We consider the new divisor 204 and the new remainder 123, and apply the division lemma to get

204 = 123 x 1 + 81

We consider the new divisor 123 and the new remainder 81,and apply the division lemma to get

123 = 81 x 1 + 42

We consider the new divisor 81 and the new remainder 42,and apply the division lemma to get

81 = 42 x 1 + 39

We consider the new divisor 42 and the new remainder 39,and apply the division lemma to get

42 = 39 x 1 + 3

We consider the new divisor 39 and the new remainder 3,and apply the division lemma to get

39 = 3 x 13 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 327 and 858 is 3

Notice that 3 = HCF(39,3) = HCF(42,39) = HCF(81,42) = HCF(123,81) = HCF(204,123) = HCF(327,204) = HCF(858,327) .
