HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 923, 621, 495 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 923, 621, 495 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 923, 621, 495 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 923, 621, 495 is 1.

HCF(923, 621, 495) = 1

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

HCF of:

Highest common factor (HCF) of 923, 621, 495 is 1.

Highest Common Factor of 923,621,495 using Euclid's algorithm

Highest Common Factor of 923,621,495 is 1

Step 1: Since 923 > 621, we apply the division lemma to 923 and 621, to get

923 = 621 x 1 + 302

Step 2: Since the reminder 621 ≠ 0, we apply division lemma to 302 and 621, to get

621 = 302 x 2 + 17

Step 3: We consider the new divisor 302 and the new remainder 17, and apply the division lemma to get

302 = 17 x 17 + 13

We consider the new divisor 17 and the new remainder 13,and apply the division lemma to get

17 = 13 x 1 + 4

We consider the new divisor 13 and the new remainder 4,and apply the division lemma to get

13 = 4 x 3 + 1

We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get

4 = 1 x 4 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 923 and 621 is 1

Notice that 1 = HCF(4,1) = HCF(13,4) = HCF(17,13) = HCF(302,17) = HCF(621,302) = HCF(923,621) .

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

Step 1: Since 495 > 1, we apply the division lemma to 495 and 1, to get

495 = 1 x 495 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 495 is 1

Notice that 1 = HCF(495,1) .
