HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 530, 732, 782 i.e. 2 the largest integer that leaves a remainder zero for all numbers.

HCF of 530, 732, 782 is 2 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 530, 732, 782 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 530, 732, 782 is 2.

HCF(530, 732, 782) = 2

Highest common factor (HCF) of 530, 732, 782 is 2.

Highest Common Factor of 530,732,782 using Euclid's algorithm

Highest Common Factor of 530,732,782 is 2

Step 1: Since 732 > 530, we apply the division lemma to 732 and 530, to get

732 = 530 x 1 + 202

Step 2: Since the reminder 530 ≠ 0, we apply division lemma to 202 and 530, to get

530 = 202 x 2 + 126

Step 3: We consider the new divisor 202 and the new remainder 126, and apply the division lemma to get

202 = 126 x 1 + 76

We consider the new divisor 126 and the new remainder 76,and apply the division lemma to get

126 = 76 x 1 + 50

We consider the new divisor 76 and the new remainder 50,and apply the division lemma to get

76 = 50 x 1 + 26

We consider the new divisor 50 and the new remainder 26,and apply the division lemma to get

50 = 26 x 1 + 24

We consider the new divisor 26 and the new remainder 24,and apply the division lemma to get

26 = 24 x 1 + 2

We consider the new divisor 24 and the new remainder 2,and apply the division lemma to get

24 = 2 x 12 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 530 and 732 is 2

Notice that 2 = HCF(24,2) = HCF(26,24) = HCF(50,26) = HCF(76,50) = HCF(126,76) = HCF(202,126) = HCF(530,202) = HCF(732,530) .

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

Step 1: Since 782 > 2, we apply the division lemma to 782 and 2, to get

782 = 2 x 391 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 782 is 2

Notice that 2 = HCF(782,2) .
