HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 69, 23, 502 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 69, 23, 502 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 69, 23, 502 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 69, 23, 502 is 1.

HCF(69, 23, 502) = 1

HCF of 69, 23, 502 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 69, 23, 502 is 1.

Highest Common Factor of 69,23,502 using Euclid's algorithm

Highest Common Factor of 69,23,502 is 1

Step 1: Since 69 > 23, we apply the division lemma to 69 and 23, to get

69 = 23 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 23, the HCF of 69 and 23 is 23

Notice that 23 = HCF(69,23) .


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

Step 1: Since 502 > 23, we apply the division lemma to 502 and 23, to get

502 = 23 x 21 + 19

Step 2: Since the reminder 23 ≠ 0, we apply division lemma to 19 and 23, to get

23 = 19 x 1 + 4

Step 3: We consider the new divisor 19 and the new remainder 4, and apply the division lemma to get

19 = 4 x 4 + 3

We consider the new divisor 4 and the new remainder 3,and apply the division lemma to get

4 = 3 x 1 + 1

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

3 = 1 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 23 and 502 is 1

Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(19,4) = HCF(23,19) = HCF(502,23) .
