HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 495, 901, 393 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 495, 901, 393 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 495, 901, 393 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 495, 901, 393 is 1.

HCF(495, 901, 393) = 1

HCF of 495, 901, 393 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 495, 901, 393 is 1.

Highest Common Factor of 495,901,393 using Euclid's algorithm

Highest Common Factor of 495,901,393 is 1

Step 1: Since 901 > 495, we apply the division lemma to 901 and 495, to get

901 = 495 x 1 + 406

Step 2: Since the reminder 495 ≠ 0, we apply division lemma to 406 and 495, to get

495 = 406 x 1 + 89

Step 3: We consider the new divisor 406 and the new remainder 89, and apply the division lemma to get

406 = 89 x 4 + 50

We consider the new divisor 89 and the new remainder 50,and apply the division lemma to get

89 = 50 x 1 + 39

We consider the new divisor 50 and the new remainder 39,and apply the division lemma to get

50 = 39 x 1 + 11

We consider the new divisor 39 and the new remainder 11,and apply the division lemma to get

39 = 11 x 3 + 6

We consider the new divisor 11 and the new remainder 6,and apply the division lemma to get

11 = 6 x 1 + 5

We consider the new divisor 6 and the new remainder 5,and apply the division lemma to get

6 = 5 x 1 + 1

We consider the new divisor 5 and the new remainder 1,and apply the division lemma to get

5 = 1 x 5 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 495 and 901 is 1

Notice that 1 = HCF(5,1) = HCF(6,5) = HCF(11,6) = HCF(39,11) = HCF(50,39) = HCF(89,50) = HCF(406,89) = HCF(495,406) = HCF(901,495) .


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

Step 1: Since 393 > 1, we apply the division lemma to 393 and 1, to get

393 = 1 x 393 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 393 is 1

Notice that 1 = HCF(393,1) .
