HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 497, 195, 436 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 497, 195, 436 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 497, 195, 436 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 497, 195, 436 is 1.

HCF(497, 195, 436) = 1

HCF of 497, 195, 436 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 497, 195, 436 is 1.

Highest Common Factor of 497,195,436 using Euclid's algorithm

Highest Common Factor of 497,195,436 is 1

Step 1: Since 497 > 195, we apply the division lemma to 497 and 195, to get

497 = 195 x 2 + 107

Step 2: Since the reminder 195 ≠ 0, we apply division lemma to 107 and 195, to get

195 = 107 x 1 + 88

Step 3: We consider the new divisor 107 and the new remainder 88, and apply the division lemma to get

107 = 88 x 1 + 19

We consider the new divisor 88 and the new remainder 19,and apply the division lemma to get

88 = 19 x 4 + 12

We consider the new divisor 19 and the new remainder 12,and apply the division lemma to get

19 = 12 x 1 + 7

We consider the new divisor 12 and the new remainder 7,and apply the division lemma to get

12 = 7 x 1 + 5

We consider the new divisor 7 and the new remainder 5,and apply the division lemma to get

7 = 5 x 1 + 2

We consider the new divisor 5 and the new remainder 2,and apply the division lemma to get

5 = 2 x 2 + 1

We consider the new divisor 2 and the new remainder 1,and apply the division lemma 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 497 and 195 is 1

Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(7,5) = HCF(12,7) = HCF(19,12) = HCF(88,19) = HCF(107,88) = HCF(195,107) = HCF(497,195) .

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

Step 1: Since 436 > 1, we apply the division lemma to 436 and 1, to get

436 = 1 x 436 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 436 is 1

Notice that 1 = HCF(436,1) .
