HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 53, 66 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 53, 66 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 53, 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 53, 66 is 1.

HCF(53, 66) = 1

HCF of 53, 66 using Euclid's algorithm

Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.

HCF of:

Highest common factor (HCF) of 53, 66 is 1.

Highest Common Factor of 53,66 using Euclid's algorithm

Highest Common Factor of 53,66 is 1

Step 1: Since 66 > 53, we apply the division lemma to 66 and 53, to get

66 = 53 x 1 + 13

Step 2: Since the reminder 53 ≠ 0, we apply division lemma to 13 and 53, to get

53 = 13 x 4 + 1

Step 3: We consider the new divisor 13 and the new remainder 1, and apply the division lemma to get

13 = 1 x 13 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 53 and 66 is 1

Notice that 1 = HCF(13,1) = HCF(53,13) = HCF(66,53) .
