HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 256, 663 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 256, 663 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 256, 663 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 256, 663 is 1.

HCF(256, 663) = 1

Highest common factor (HCF) of 256, 663 is 1.

Highest Common Factor of 256,663 using Euclid's algorithm

Highest Common Factor of 256,663 is 1

Step 1: Since 663 > 256, we apply the division lemma to 663 and 256, to get

663 = 256 x 2 + 151

Step 2: Since the reminder 256 ≠ 0, we apply division lemma to 151 and 256, to get

256 = 151 x 1 + 105

Step 3: We consider the new divisor 151 and the new remainder 105, and apply the division lemma to get

151 = 105 x 1 + 46

We consider the new divisor 105 and the new remainder 46,and apply the division lemma to get

105 = 46 x 2 + 13

We consider the new divisor 46 and the new remainder 13,and apply the division lemma to get

46 = 13 x 3 + 7

We consider the new divisor 13 and the new remainder 7,and apply the division lemma to get

13 = 7 x 1 + 6

We consider the new divisor 7 and the new remainder 6,and apply the division lemma to get

7 = 6 x 1 + 1

We consider the new divisor 6 and the new remainder 1,and apply the division lemma to get

6 = 1 x 6 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 256 and 663 is 1

Notice that 1 = HCF(6,1) = HCF(7,6) = HCF(13,7) = HCF(46,13) = HCF(105,46) = HCF(151,105) = HCF(256,151) = HCF(663,256) .
