HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 497, 929, 159 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 497, 929, 159 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, 929, 159 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, 929, 159 is 1.

HCF(497, 929, 159) = 1

HCF of 497, 929, 159 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, 929, 159 is 1.

Highest Common Factor of 497,929,159 using Euclid's algorithm

Highest Common Factor of 497,929,159 is 1

Step 1: Since 929 > 497, we apply the division lemma to 929 and 497, to get

929 = 497 x 1 + 432

Step 2: Since the reminder 497 ≠ 0, we apply division lemma to 432 and 497, to get

497 = 432 x 1 + 65

Step 3: We consider the new divisor 432 and the new remainder 65, and apply the division lemma to get

432 = 65 x 6 + 42

We consider the new divisor 65 and the new remainder 42,and apply the division lemma to get

65 = 42 x 1 + 23

We consider the new divisor 42 and the new remainder 23,and apply the division lemma to get

42 = 23 x 1 + 19

We consider the new divisor 23 and the new remainder 19,and apply the division lemma to get

23 = 19 x 1 + 4

We consider the new divisor 19 and the new remainder 4,and apply the division lemma to get

19 = 4 x 4 + 3

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

4 = 3 x 1 + 1

We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get

3 = 1 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 497 and 929 is 1

Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(19,4) = HCF(23,19) = HCF(42,23) = HCF(65,42) = HCF(432,65) = HCF(497,432) = HCF(929,497) .

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

Step 1: Since 159 > 1, we apply the division lemma to 159 and 1, to get

159 = 1 x 159 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 159 is 1

Notice that 1 = HCF(159,1) .
