HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 342, 635, 477 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 342, 635, 477 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 342, 635, 477 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 342, 635, 477 is 1.

HCF(342, 635, 477) = 1

HCF of 342, 635, 477 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 342, 635, 477 is 1.

Highest Common Factor of 342,635,477 using Euclid's algorithm

Highest Common Factor of 342,635,477 is 1

Step 1: Since 635 > 342, we apply the division lemma to 635 and 342, to get

635 = 342 x 1 + 293

Step 2: Since the reminder 342 ≠ 0, we apply division lemma to 293 and 342, to get

342 = 293 x 1 + 49

Step 3: We consider the new divisor 293 and the new remainder 49, and apply the division lemma to get

293 = 49 x 5 + 48

We consider the new divisor 49 and the new remainder 48,and apply the division lemma to get

49 = 48 x 1 + 1

We consider the new divisor 48 and the new remainder 1,and apply the division lemma to get

48 = 1 x 48 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 342 and 635 is 1

Notice that 1 = HCF(48,1) = HCF(49,48) = HCF(293,49) = HCF(342,293) = HCF(635,342) .


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

Step 1: Since 477 > 1, we apply the division lemma to 477 and 1, to get

477 = 1 x 477 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 477 is 1

Notice that 1 = HCF(477,1) .
