HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 803, 657 i.e. 73 the largest integer that leaves a remainder zero for all numbers.

HCF of 803, 657 is 73 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 803, 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 803, 657 is 73.

HCF(803, 657) = 73

Highest common factor (HCF) of 803, 657 is 73.

Highest Common Factor of 803,657 using Euclid's algorithm

Highest Common Factor of 803,657 is 73

Step 1: Since 803 > 657, we apply the division lemma to 803 and 657, to get

803 = 657 x 1 + 146

Step 2: Since the reminder 657 ≠ 0, we apply division lemma to 146 and 657, to get

657 = 146 x 4 + 73

Step 3: We consider the new divisor 146 and the new remainder 73, and apply the division lemma to get

146 = 73 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 73, the HCF of 803 and 657 is 73

Notice that 73 = HCF(146,73) = HCF(657,146) = HCF(803,657) .
