HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 576, 797, 30 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 576, 797, 30 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 576, 797, 30 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 576, 797, 30 is 1.

HCF(576, 797, 30) = 1

Highest common factor (HCF) of 576, 797, 30 is 1.

Highest Common Factor of 576,797,30 using Euclid's algorithm

Highest Common Factor of 576,797,30 is 1

Step 1: Since 797 > 576, we apply the division lemma to 797 and 576, to get

797 = 576 x 1 + 221

Step 2: Since the reminder 576 ≠ 0, we apply division lemma to 221 and 576, to get

576 = 221 x 2 + 134

Step 3: We consider the new divisor 221 and the new remainder 134, and apply the division lemma to get

221 = 134 x 1 + 87

We consider the new divisor 134 and the new remainder 87,and apply the division lemma to get

134 = 87 x 1 + 47

We consider the new divisor 87 and the new remainder 47,and apply the division lemma to get

87 = 47 x 1 + 40

We consider the new divisor 47 and the new remainder 40,and apply the division lemma to get

47 = 40 x 1 + 7

We consider the new divisor 40 and the new remainder 7,and apply the division lemma to get

40 = 7 x 5 + 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 576 and 797 is 1

Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(7,5) = HCF(40,7) = HCF(47,40) = HCF(87,47) = HCF(134,87) = HCF(221,134) = HCF(576,221) = HCF(797,576) .

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

Step 1: Since 30 > 1, we apply the division lemma to 30 and 1, to get

30 = 1 x 30 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 30 is 1

Notice that 1 = HCF(30,1) .
