HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 530, 423, 12 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 530, 423, 12 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 530, 423, 12 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, 423, 12 is 1.

HCF(530, 423, 12) = 1

Highest common factor (HCF) of 530, 423, 12 is 1.

Highest Common Factor of 530,423,12 using Euclid's algorithm

Highest Common Factor of 530,423,12 is 1

Step 1: Since 530 > 423, we apply the division lemma to 530 and 423, to get

530 = 423 x 1 + 107

Step 2: Since the reminder 423 ≠ 0, we apply division lemma to 107 and 423, to get

423 = 107 x 3 + 102

Step 3: We consider the new divisor 107 and the new remainder 102, and apply the division lemma to get

107 = 102 x 1 + 5

We consider the new divisor 102 and the new remainder 5,and apply the division lemma to get

102 = 5 x 20 + 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 530 and 423 is 1

Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(102,5) = HCF(107,102) = HCF(423,107) = HCF(530,423) .

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

Step 1: Since 12 > 1, we apply the division lemma to 12 and 1, to get

12 = 1 x 12 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 12 is 1

Notice that 1 = HCF(12,1) .
