HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 721, 527, 494 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 721, 527, 494 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 721, 527, 494 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 721, 527, 494 is 1.

HCF(721, 527, 494) = 1

Highest common factor (HCF) of 721, 527, 494 is 1.

Highest Common Factor of 721,527,494 using Euclid's algorithm

Highest Common Factor of 721,527,494 is 1

Step 1: Since 721 > 527, we apply the division lemma to 721 and 527, to get

721 = 527 x 1 + 194

Step 2: Since the reminder 527 ≠ 0, we apply division lemma to 194 and 527, to get

527 = 194 x 2 + 139

Step 3: We consider the new divisor 194 and the new remainder 139, and apply the division lemma to get

194 = 139 x 1 + 55

We consider the new divisor 139 and the new remainder 55,and apply the division lemma to get

139 = 55 x 2 + 29

We consider the new divisor 55 and the new remainder 29,and apply the division lemma to get

55 = 29 x 1 + 26

We consider the new divisor 29 and the new remainder 26,and apply the division lemma to get

29 = 26 x 1 + 3

We consider the new divisor 26 and the new remainder 3,and apply the division lemma to get

26 = 3 x 8 + 2

We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get

3 = 2 x 1 + 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 721 and 527 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(26,3) = HCF(29,26) = HCF(55,29) = HCF(139,55) = HCF(194,139) = HCF(527,194) = HCF(721,527) .

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

Step 1: Since 494 > 1, we apply the division lemma to 494 and 1, to get

494 = 1 x 494 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 494 is 1

Notice that 1 = HCF(494,1) .
