HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 823, 701, 497 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 823, 701, 497 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 823, 701, 497 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 823, 701, 497 is 1.

HCF(823, 701, 497) = 1

Highest common factor (HCF) of 823, 701, 497 is 1.

Highest Common Factor of 823,701,497 using Euclid's algorithm

Highest Common Factor of 823,701,497 is 1

Step 1: Since 823 > 701, we apply the division lemma to 823 and 701, to get

823 = 701 x 1 + 122

Step 2: Since the reminder 701 ≠ 0, we apply division lemma to 122 and 701, to get

701 = 122 x 5 + 91

Step 3: We consider the new divisor 122 and the new remainder 91, and apply the division lemma to get

122 = 91 x 1 + 31

We consider the new divisor 91 and the new remainder 31,and apply the division lemma to get

91 = 31 x 2 + 29

We consider the new divisor 31 and the new remainder 29,and apply the division lemma to get

31 = 29 x 1 + 2

We consider the new divisor 29 and the new remainder 2,and apply the division lemma to get

29 = 2 x 14 + 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 823 and 701 is 1

Notice that 1 = HCF(2,1) = HCF(29,2) = HCF(31,29) = HCF(91,31) = HCF(122,91) = HCF(701,122) = HCF(823,701) .

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

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

497 = 1 x 497 + 0

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

Notice that 1 = HCF(497,1) .
