HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 424, 214, 635 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 424, 214, 635 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 424, 214, 635 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 424, 214, 635 is 1.

HCF(424, 214, 635) = 1

HCF of 424, 214, 635 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 424, 214, 635 is 1.

Highest Common Factor of 424,214,635 using Euclid's algorithm

Highest Common Factor of 424,214,635 is 1

Step 1: Since 424 > 214, we apply the division lemma to 424 and 214, to get

424 = 214 x 1 + 210

Step 2: Since the reminder 214 ≠ 0, we apply division lemma to 210 and 214, to get

214 = 210 x 1 + 4

Step 3: We consider the new divisor 210 and the new remainder 4, and apply the division lemma to get

210 = 4 x 52 + 2

We consider the new divisor 4 and the new remainder 2, and apply the division lemma to get

4 = 2 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 424 and 214 is 2

Notice that 2 = HCF(4,2) = HCF(210,4) = HCF(214,210) = HCF(424,214) .

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

Step 1: Since 635 > 2, we apply the division lemma to 635 and 2, to get

635 = 2 x 317 + 1

Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, to get

2 = 1 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 2 and 635 is 1

Notice that 1 = HCF(2,1) = HCF(635,2) .
