HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 501, 759, 66 i.e. 3 the largest integer that leaves a remainder zero for all numbers.

HCF of 501, 759, 66 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 501, 759, 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 501, 759, 66 is 3.

HCF(501, 759, 66) = 3

HCF of 501, 759, 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 501, 759, 66 is 3.

Highest Common Factor of 501,759,66 using Euclid's algorithm

Highest Common Factor of 501,759,66 is 3

Step 1: Since 759 > 501, we apply the division lemma to 759 and 501, to get

759 = 501 x 1 + 258

Step 2: Since the reminder 501 ≠ 0, we apply division lemma to 258 and 501, to get

501 = 258 x 1 + 243

Step 3: We consider the new divisor 258 and the new remainder 243, and apply the division lemma to get

258 = 243 x 1 + 15

We consider the new divisor 243 and the new remainder 15,and apply the division lemma to get

243 = 15 x 16 + 3

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

15 = 3 x 5 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 501 and 759 is 3

Notice that 3 = HCF(15,3) = HCF(243,15) = HCF(258,243) = HCF(501,258) = HCF(759,501) .


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

Step 1: Since 66 > 3, we apply the division lemma to 66 and 3, to get

66 = 3 x 22 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 3 and 66 is 3

Notice that 3 = HCF(66,3) .
